Question

Write the complex waveform expression from this data: Vpk​=20, Frequency (Hz) = 2000, Phase (Rad) = -\pi A. 20sin(4000πt−π) B. 20cos(4000πt+π) C. 20sin(4000πt+π) D. 20cos(4000πt−π)

Answer 1

The complex waveform expression can be written as 20sin(4000πt+π).

Step-by-step explanation:

The complex waveform expression can be written as C. 20sin(4000πt+π).

From the given data, we have Vpk = 20, Frequency(Hz) = 2000, and Phase(Rad) = -π.

Using the formula V(t) = Vpk * sin(2πft + θ), where Vpk is the peak voltage, f is the frequency, t is time, and θ is the phase angle, we can substitute the given values to obtain the waveform expression.

V(t) = 20 * sin(2π * 2000t - π)

Simplifying further, we get V(t) = 20 * sin(4000πt + π).
