The frequency of the clock signal applied to the rising

Home » Digital Electronics » Digital electronics miscellaneous » Question

The frequency of the clock signal applied to the rising edge triggered D flip-flop shown below is 10 kHz. What is the frequency of the signal available at Q?

1. 2.5 kHz
2. 5 kHz
3. 10 kHz
4. 20 kHz

Correct Option: B

Output frequency = Fs 2 = 10 kHz 2 = 5 kHz

Output frequency =	F_s	=	10 kHz	=	5 kHz
	2		2
