Question

What does the triangle on the clock input of a J-K flip-flop mean?

(a) Level enabled

(b) Edge triggered

(c) Both Level enabled & Edge triggered

(d) Level triggered

This question was posed to me by my school principal while I was bunking the class.

Enquiry is from Triggering of Flip Flops in division Flip-Flops of Digital Circuits

Answer 1

Right option is (b) Edge triggered

The best I can explain: The triangle on the clock input of a J-K flip-flop mean edge triggered. Whereas the absence of triangle symbol implies that the flip-flop is level-triggered.
