Suppose you have a 16times4 encoder How many OR gates need t

Suppose you have a 16times4 encoder. How many OR gates need to be activated in the encoder? (12 is 1100_2 in binary.)

Solution

Ans(18). Two or gate required.

We know that the Binary Encoderconverts one of 2^n inputs into an n-bitoutput. Then a binary encoder has fewer output bits than the input code. Binary encoders are useful for efficiently compressing data and that can be constructed by simple AND or OR gates.
