Question: 1. Given x (t) = 2 cos (4 t), determine Amplitude= Period= Phase shift = Time shift = Sketch the function for one period; you

1. Given x (t) = 2 cos (4 t), determine

Amplitude= Period= Phase shift = Time shift =

Sketch the function for one period; you must label at least four points in the graph.

2. Given x (t) = cos (4 t - ), determine

Amplitude= Period= Phase shift = Time shift =

Sketch the function for one period; you must label at least four points in the graph.

NOTE: Time shift = (phase shift)/ (angular frequency)
