Amplitude, Period, Phase Shift and Frequency . Some functions (like Sine and Cosine) repeat forever and are called Periodic Functions.. The Period goes from one peak to the next (or from any point to the next matching point):. The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2.
To calculate the phase shift, you need the frequency and period of the waves. For example, an electronic oscillator may produce sine waves at a frequency of 100 Hz. Dividing the frequency into 1 gives the period, or duration of each cycle, so 1/100 gives a period of 0.01 seconds.
From the phase-shift computations, I know that the graph is shifted to the left by , so I'll shift the y-axis to the right by . and re-number the x-axis again. This is the last bit of computation, so this is my final graph:

Phase Difference and Phase Shift Phase Difference is used to describe the difference in degrees or radians when two or more alternating quantities reach their maximum or zero values Previously we saw that a Sinusoidal Waveform is an alternating quantity that can be presented graphically in the time domain along an horizontal zero axis.
The amount of phase shift will be different for various circuits as a result of their unique designs. One thing you can do is choose a circuit design with minimal phase shift and then visually measure the phase shift with an oscilloscope. You can calculate the phase shift by measuring the circuit’s input signal with your oscilloscope’s ...
The horizontal shift is C. In mathematics, a horizontal shift may also be referred to as a phase shift.* (see page end) The easiest way to determine horizontal shift is to determine by how many units the "starting point" (0,0) of a standard sine curve, y = sin(x), has moved to the right or left.
