CRO waveform is disturbed due to _____________

A. Capacitor banks

B. RTL triggering

C. TTL triggering

D. Voltage sources

This question was addressed to me in an interview for job.

Asked question is from TTL Triggering topic in chapter Oscilloscopes of Electrical Measurements

The correct answer is C. TTL triggering

To explain I would say: In a Cathode Ray Oscilloscope, the waveform is affected as a result of TTL trigger mode. The lead inductance of the ground along with probe capacitance results in a resonance circuit.
