Amplitude is the factor by which a function is stretched vertically. The period of a repeating graph is the width of each repeat. The phase shift is the amount that the graph is moved horizontally.

The phase shift formula for a trigonometric function, such as y = Asin(Bx - C) + D or y = Acos(Bx - C) + D, is represented as C / B. If C / B is positive, the curve moves right, and if it is negative, the curve moves lef...

The main advantage of phase shift keying is that it allows data to be carried along a radio communications signal much more efficiently than with frequent shift keying. PSK is a digital modulation scheme that transports ...
