What is the function of a decade counter?
- A.It produces one output pulse for every 10 input pulses (correct answer)
- B.It decodes a decimal number for display on a seven-segment LED display
- C.It produces 10 output pulses for every input pulse
- D.It decodes a binary number for display on a seven-segment LED display
WhyA decade counter produces one output pulse for every 10 input pulses. A decade counter produces one output pulse for every 10 input pulses, dividing the input pulse rate by 10, answer A. It doesn't produce 10 output pulses per input pulse, that's the opposite relationship, and decoding a number for display on a seven-segment LED is a separate function performed by a different kind of circuit (a decoder), not the counter itself.
