What is the purpose of a prescaler circuit?
A. Converts the output of a JK flip-flop to that of an RS flip-flop.
B. Multiplies an HF signal so a low-frequency counter can display the operating frequency.
C. Prevents oscillation in a low frequency counter circuit.
D. Divides an HF signal so that a low-frequency counter can display the operating frequency.
