Question:medium

For a clock frequency of 20 MHz, the output frequency of a flip-flop is:

Show Hint

A single flip-flop operating in toggle mode always divides the input frequency by 2 (\(f_{\text{out}} = \frac{f_{\text{clk}}}{2}\)). Connecting \(N\) flip-flops in a cascade chain creates a ripple counter that divides the frequency by \(2^N\).
