logic gates

There are digital circuits which either allow a signal to pass through or stop it. The circuits other wise called as gate allows the signal to pass only when some logical condition are satisfied. Under such condition the circuits are called logic gates...

Logic Gates - The basic building blocks for a complex digital system are known as logic gates. A gate is a simple electronic circuit or device that performs logical functions. It has one or more inputs and one output gate and are..

x.y' + x.z + y.z' A Boolean expression can be regarded as a Boolean function since it has a unique value, either 0 or 1. The postulates, theorems or Boolean expressions in Boolean algebra hold good when the operation '+' and '.', the symbols '1' and '0' are interchanged, this is called principle ..

A.C.voltage gain (A V a c ) is defined as the ratio of the change in output voltage ( D V C ) to the change in input voltage ( D V i ). Here negative sign shows the phase reversal of output. A.C. Power gain is defined as the ratio of the change in output power to the change in input power i.e., a.c..
