Exclusive-NOR Gate The operation of Exclusive NOR gate is reciprocal to the Exclusive OR gate’s operation. As the basic AND gate implements the Boolean addition , while OR gate implements Boolean multiplication and NOT implements inversion function , there is no such Boolean function defined by the XNOR.This can be derived by basic gates (AND , OR ,NOT).Below shows the diagram of EX-NOR constructed from EX-OR gate. The logic symbol and Boolean expression for the XNOR gate is shown below....

This system uses FM (Frequency Modulation) for transmission. If you press any push button then corresponding code is generated at transmission section.

FM Rx module receives this serial data and fed to the decoder to produce the corresponding output. FM Remote Encoder and Decoder Circuit Diagram: Transmitter Section: Circuit Components:...

Introduction Although the thyristor is extensively used in high power applications, it always suffered from being a semi-controlled device. Even though it could be switched ON by applying a gate signal, it has to be turned OFF by interrupting the main current using a commutation circuit. In case of DC to DC and DC to AC conversion circuits, this becomes a serious deficiency with thyristor due to the absence of natural current zero (as in case of AC circuits)....
