Module 1.1 Sinusoidal Waveforms Learn how the shape of the waveform is related to the amplitude, frequency, and
reference phase angle of a sinusoidal wave.
Module 1.1
Sinusoidal Waveforms
Instructions
The waveform shown in red is a reference wave given by $y = 5\cos4\pi t$:
amplitude = 5 volts, $f = 2$ Hz, and $\theta_0 = 0$.
For comparison, you can generate and display in blue a waveform given by
$y = A\cos(2\pi ft + \theta_0)$
by specifying its attributes in the Input Panel.
Input for blue wave
Amplitude $A = 4.118$ [volts]
Frequency $f = 1.3825$ [Hz]
Angle $\theta_0 = 50.796$
$A = 5$ [volts]
$f = 2$ [Hz]
$\theta_0 = 0^\circ$
$A = 4.118$ [volts]
$f = 1.3825$ [Hz]
$\theta_0 = 50.796^\circ$
