The horizontal plates of a CRO are supplied with _____________ to observe the waveform of signal?
Correct answer: C. Sawtooth wave
- A. Sinusoidal wave
- B. Cosine wave
- C. Sawtooth wave
- D. None of the above
Explanation
The CRO horizontal plates receive a sawtooth time-base voltage, which moves the spot uniformly across the screen and then rapidly returns it. This allows the signal waveform to be displayed against time.
