Digital electronics is branch of electronics which deals with digital signals to accomplish the tasks. The digital signals are the signals which are represented using the binary language, i.e., 0’s and 1’s.The digital circuits are implemented using logic gates like AND, OR, NOT, NAND, NOR, XOR and XNOR which can ...

A diac is a two-terminal, three-layer, bidirectional device which can be switched from OFF state to ON state for both positive and negative polarity of the supply voltage.Constructional Details of the DiacThe basic structure of a Diac is similar to a BJT transistor. The only difference is that there is ... Read More

In practice, a rectifier is used to produce pure DC supply in electronic circuits. But the output of a rectifier is not pure DC, it has pulsations, i.e., it contains AC and DC components. The AC component is undesirable and must be removed. For this, a filter circuit is used."A ... Read More
