 Encoders An encoder is a combinational circuit that performs the inverse operation of a decoder. If a device output code has fewer bits than the input code has, the device is usually called an encoder. e.g. 2n-to-n, priority encoders.

 Concept of Sequential Logic A sequential circuit as seen in the last page, is combinational logic with some feedback to maintain its current value, like a memory cell. To understand the basics let's consider the basic feedback logic circuit below, which is a simple NOT gate whose output is connected to its input.
