Which concept describes the output count increasing by one with every input pulse due to a toggling action?

Which concept describes the output count increasing by one with every input pulse due to a toggling action?

• A. Counter
• B. Frequency Division/Divider
• C. Counter Triggering Method
• D. Oscillator

Answer: (C)

Counting is the idea being tested. When a counter receives an input pulse, it uses flip-flops that toggle on each clock edge, so the least significant bit flips every pulse. When that bit goes from 1 back to 0, it causes the next bit to toggle, and so on up the chain. The net result is a binary number that increases by one for every input pulse. This is different from a frequency divider, which uses toggling to produce a slower waveform (the output frequency drops, not the count increasing with each pulse). An oscillator, meanwhile, just generates a continuous signal, not a count of input events. The term “counter triggering method” isn’t the standard way to describe this counting action; the key concept here is the counting behavior produced by toggling flip-flops in a counter.
