What happens to the parallel output word in an asynchronous binary dow

1.	What happens to the parallel output word in an asynchronous binary down counter whenever a clock pulse occurs?(a) The output increases by 1(b) The output decreases by 1(c) The output word increases by 2(d) The output word decreases by 2I got this question during an online interview.Origin of the question is Asynchronous Counter topic in division Counters of Digital Circuits
Answer» Correct ANSWER is (b) The output decreases by 1 Easiest EXPLANATION: In an ASYNCHRONOUS counter, there isn’t any CLOCK input. The output of 1^st flip-flop is given to second flip-flop as clock input. So, in case of binary down counter the output WORD decreases by 1.
