The mod-number of the asynchronous counter shown in the figure is
-
- 24
- 48
- 25
- 36
Correct Option: A
It is a 5 bit ripple counter. At 11000, output of NAND gate is LOW. This will clear all FF. So it is a Mod – 24 counter.
Note that when 11000 occur, the CLR input is activated and all FF are immediately cleared. So it is a MOD 24 counter not MOD 25.
