Digital Electronics MCQs

A list of top frequently asked Digital Electronics Interview Questions and answers are given below. The difference between latches and Flip-flop is that the latches are level triggered and flip-flops are edge triggered. In latches level triggered means that the output of the latches changes as we change the input and edge triggered means that control signal only changes its state when goes from low to high or high to low. The system which has a base 2 is known as the binary system and it consists of only two digits 0 and 1. In this consist of three bits, we start writing the numbers from the rightmost bit power as 0 then the second bit as power 1 and the last as power 2. So, we can represent a decimal number as.
