Question

A sine wave with an rms value of 10.6 v is riding on a dc level of 24 v. what are the maxi- mum and minimum values of the resulting waveform?

Answer 1

Amplitude of a sine wave = RMS voltage*Sqrt (2) = 10.6*Sqrt (2) = 14.99 V ≈ 15 V
Therefore,
Range of values of resulting wave = 24+/- Amplitude
Then,
Maximum value of the resulting wave = 24+15 = 39 V
Minimum of the resulting wave = 24-15 = 9 V
