Question
What is the function of a decade counter?
Answer Options
- A) It produces one output pulse for every 10 input pulses
- 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
Correct Answer: A
Explanation
A counter is a sequential digital circuit composed of cascaded flip-flops that cycles through a predictable sequence of states when clocked. The count sequence is determined by the number of output states it is designed to utilize before resetting.
A decade counter is specifically designed to count from zero through nine (10 distinct states) and then reset to zero. Its primary function is therefore to produce one output pulse for every 10 input pulses. This makes the decade counter a valuable circuit for frequency division by a factor of 10 and in decimal counting systems, such as digital frequency displays or decimal counters.
