Digital circuits work on the basis of a transistor being used as a switch. Consider a light switch, a transistor can be considered almost the same and in some circuits transistors are used to control large amounts of power with very little input power being used.

Look at figure 1 below. Here are two crude transistor switch circuits. This load could also be replaced by a small light bulb, relay or LED in conjunction with a resistor of suitable value. In any event the bulb or led would light or the relay would close. Figure 1. The output is always the opposite to the input and in digital basics terms this is called an "inverter" a very important property. Now looking at Q2 and Q3 to the right of the schematic we simply have two inverters chained one after the other.

Here if you think it through the final output 2 from Q3 will always follow the input given to Q2. This in digital basics is your basic transistor switch. Logic Blocks in Digital Basics Depending upon how these "switches" and "inverters" are arranged in integrated circuits we are able to obtain "logic blocks" to perform various tasks. In figure 2 we look at some of the most basic logic blocks. Figure 2.

In the second set of switches A, B, and C they are arranged in "parallel" so that for any input to reach the output any one of the switches may be closed. These are considered the basic building blocks in digital logic. Here in figure 3 we examine the digital basics in schematic form. Figure 3. Firstly the "1's" and the "0's" or otherwise known as the "ones" and "zeros". A "1" is a HIGH voltage usually the voltage supply and the "0" is no voltage or ground potential. Other people prefer designating "H" and "L" for high and low instead of the "1's" and the "0's".

Stick with which system you feel most comfortable.

Wingdings : Information representation Elementary storage units inside computer are electronic switches. Each switch holds one of two states: on 1 or off 0. We use a bit bi nary digi t0 or 1, to represent the state. ON OFF 4. Symbol : Information representation Storage units can be grouped together to cater for larger range of numbers. Example: 2 switches to represent 4 values. For M values, bits are needed. Equation : Other Number Systems Binary base 2 : weights in powers-of Binary digits bits : 0,1.

Acknowledgement : Repeated Division-by-2 Method To convert a whole number to binary, use successive division by 2 until the quotient is 0. The remainders form the answer, with the first remainder as the least significant bit LSB and the last as the most significant bit MSB.

Analog processing is usually faster. Traditional electronic systems were mostly analog in nature. How its made? In Boolean Logic, 0 and 1. Transistor as a switch is the building block of Digital Electronics. Where are they used? What are the inputs? Which logic gate should be used? Complexity in a digital design : Complexity in a digital design Complexity can, and generally does, surpass human capability. Provides motivation for computer-based design techniques.

Most engineering work is done with CAD packages. Digital Circuits : Digital Circuits A digital circuit is often constructed from small electronic circui ts called logic gate s that can be used to create combinational logic. Each logic gate represents a function of boolean logic.

A logic gate is an arrangement of electrically controlled switches, better known as transistors. The output of a logic gate is an electrical flow or voltage, that can, in turn, control more logic gates.

Integrated circuits are the least expensive way to make logic gates in large volumes.After you enable Flash, refresh this page and the presentation should play. Get the plugin now. Toggle navigation.
