Question

Difference between encoder and priority encoder

Answer 1

Encoder: it is the device which transform data in to bits. it is the process of placing sequence of different format into special character in order to be able to transmission and storage. 
Also In case of encoder binary code is used as an input it have more than one inputs line but only one as activated at a given time.

while In case of priority encoder the algorithm compress many binary inputs the result of which  smaller number of outputs can be achieved.

Answer 2

Answer:

Binary Encoder converts one of 2n inputs into an n-bit output. It has fewer output bits than the input code. The Priority Encoder is another type of combinational circuit similar to a binary encoder, except that it generates an output code based on the highest prioritized input.
