Last Answer : Answer : A
Description : Calculate the total rise time for a fiber-optic system if the transmitter, receiver, and cable each have a rise time of 50 nanoseconds.
Last Answer : 86.6 nanoseconds
Description : What is the bandwidth of a first-order LPF with a rise time of 350 nanoseconds?
Last Answer : 1 MHz
Description : An eight stage ripple counter uses a flip-flop with propagation delay of 75 nanoseconds. The pulse width of the strobe is 50ns. The frequency of the input signal which can be used for proper operation of the counter is approximately (A) 1 MHz. (B) 500 MHz. (C) 2 MHz. (D) 4 MHz.
Last Answer : Maximum time taken for all flip-flops to stabilize is 75ns x 8 + 50 = 650ns. Frequency of operation must be less than 1/650ns = 1.5 MHz.
