Oscilloscope trace ? select the trace feature that proves clipping has started. Use this to support: Distinguish amplitude modulation from frequency modulation.
- A.oscilloscope trace: upper and lower flat sections show amplifier saturation for Amplitude and frequency modulation.
- B.oscilloscope trace: confuses clipping with ordinary amplification.
- C.oscilloscope trace: uses peak spacing instead of amplitude limit.
- D.oscilloscope trace: ignores the supply rail limit.
Model answer
What a good answer should say
- The correct option is oscilloscope trace: upper and lower flat sections show amplifier saturation for Amplitude and frequency modulation.
Explanation
Why this works
This is the best answer because the oscilloscope trace context requires that exact electronics relationship. The other options are incorrect because they use a different component, reverse the circuit behaviour, or omit the output interpretation required for Amplitude and frequency modulation.
