Question

.Draw the following sine wave in the time domain, showing amplitude and phase:

s(t) = 3sin (2π2t + π)

Answer 1

Answer with Explanation:

Part 1)

The given sine wave is as

`y=3sin(2\pi t+\pi)`

The graphical representation of the wave is shown in the attached figure:

Part 2)

For a general wave equation
`y(t)=Asin(\omega t+\phi )`

'A' is defined as amplitude of the wave

`(\omega t+\phi )` is defined as phase of the wave

Upon comparing with the given wave function we observe

1) Amplitude of the given wave is 3

2) Phase of the given wave
`(2\pi t+\phi )`
