Current: Current is the flow of electrons through a conductor or semiconductor, measured in Amperes or Amps. Some materials conduct current better than others; these are known as conductors, semiconductors, and insulators. Current flow is from positive to negative. Power: Power determines how much work a circuit can do.

Ground: Minimum voltage reference level. True ground connects to the earth but the circuits we work with may not actually be connected to the earth, especially if they are battery powered. Technically this is known as a floating ground. Resistance Resistors are measured in Ohm and come between conductors, which conduct easily and insulators which don't conduct.

The main function of resistors in a circuit is to control the flow of current and voltage drops to other components. For example; if too much current flows through an LED it is destroyed and will not light, so a resistor is used to limit the current but not so big as it will limit all the current.

An Introduction to Logic Gates

When a current flows through a resistor, energy is wasted and the resistor heats up. This will only be noticed if the resistor is working at its maximum power rating.

The greater the current flowing through the resistor the hotter it gets. A battery or power supply has to do work to force electrons through the resistor and this work ends up as heat energy in the resistor. An important property to know about resistors is how much heat energy it can withstand before it's damaged or causes a fire. Resistors can dissipate different powers Watts depending on its power rating and the current passing through.

It is difficult to make a resistor to an exact value, so resistances are given a tolerance. This is expressed as being plus or minus a percentage. In circuit diagrams you will often see an 'R' instead of omega to represent ohms. Instead of writing the resistance on its body, which would often be too small to read, a color code is used. Different colors represent the numbers 0 to 9. The first two colored bands on the body are the first two digits of the resistance, and the third band is the 'multiplier'.

Multiplier just means the number of zeroes to add after the first two digits. Red represents the number 2, so a resistor with red, red, red bands has a resistance of 2 followed by 2 followed by 2 zeroes, which is ohms or 2.

All resistors have a tolerance which is shown by the last band. Resistance between leads is maximum resistance of potentiometer. With linear pots, resistance varies directly with the rotation of the knob while with logarithmic pots; resistance varies exponentially with the rotation of the knob.

The sum of the current entering a junction equals the sum of the current exiting a junction. A circuit with a break in it is called an open circuit. A circuit without enough resistance in its load is called a short circuit. Switching an LED is shown at the example schematic below. Single path for electrons to flow - all components share the same current. Total resistance of circuit is equal to sum of individual resistances.The following slides are supplied to aid control educators in the preparation and presentation of course material.

The slides are closely related to the text, aiding the educator in producing carefully integrated course material. Alternatively for the individual reader, the slides provide a summary of key control concepts presented in the text.

Operations Management Course description : This operations management course is intended to be a survey of the operating practices and procedures found in both manufacturing and service delivery firms.

We will focus our attention on those business processes and procedures used to transform inputs into finished goods and services. Operations management focuses on the systematic planning, design, and operation of all processes required for the production of goods and the delivery of services. Thus, operations management spans almost all the real value-added activities of an organization including product and process design, customer order management, production, and service delivery.

Operations management also includes many supporting value-added activities such as purchasing, material requirements planning, inventory management, project management, and process improvement. These and related topics will be covered. Chapter 1 Introduction to Operations Management.

Sinct Using trigonometric relation sinA. In order to generate AM wavesit is required that series of current pulses be Applied to a tuned resonant circuit, then each pulse would induce a damped Oscillation in the tuned circuit. The oscillation would have initial amplitude Prop. To size of current pulse and a decay rate dependant on time constant of tuned circuit.

Since continous pulses are applied, each will form a unique sine Prop. To amplitude of each of those pulses. Transistor modulator Base modulated class c amplifier Collector modulated class c amplifier. It is used to produce low-level modulation in equipment operating at very low power levels. In figurethe bias on Q1 is established by the voltage. With the rf carrier input at T1, and no modulating signal, the circuit acts as a standard rf amplifier.

When a modulating signal is injected through C1, it develops a voltage across R1 that adds to or subtracts from the bias on Q1. This change in bias changes the gain of Q1, causing more or less energy to be supplied to the collector tank circuit. The tank circuit develops the modulation envelope as the rf frequency and af modulating frequency are mixed in the collector circuit.

Again, this action is identical to that in the plate modulator. Figure Because of the extremely low-level signals required to. Collector modulation -Adv.

Over base modulation Better linearity Higher collector efficiency Collector saturation prevents. But requires more modulating input power. In figurethe rf carrier is applied to the base of modulator Q1. The modulating signal is applied to the collector in series with the collector supply voltage through T3.

The output is then taken from the secondary of T2. With no modulating signal, Q1 acts as an rf amplifier for the carrier frequency. When the modulation signal is applied, it adds to or subtracts from the collector supply voltage. This causes the rf current pulses of the collector to vary in amplitude with the collector supply voltage. These collector current pulses cause oscillations in the tank circuit C4 and the primary of T2. The tank circuit is tuned to.

For class A, there will be a dc component of collector current adoes not depend on the base voltage. The carrier voltage is applied to the gates in phase; the. The modulated output currents of the FETs are combined in the centre-tapped primary of the push-pull output transformer, they subtract as indicated. If the system is symmetrical, carrier will be cancelled out, however this is not the case, its heavily suppressed by 45dB or so.

The output of the balanced modulator contains the 2 sidebands and some extra components which are eradicated by transformers secondary winding. If perfect symmetry is assumed it should be understood that the 2 devices used in balanced modulator must be matched, whether transistors or diodes ; the prop. Constants will therefore be the same for both FETs and may be called a,b,c as prev. A linear amplifier is an electronic circuit whose output is proportional to its input, but capable of delivering more power into a load.

A frequency synthesizer is an electronic system for generating any of a range of frequencies from a single fixed timebase or oscillator.This is core course of Electrical and Elecronic Engineering and Information System Engineering that presents basic tools for the design of digital circuits.
