A simplex arrangement allows communication in one direction only. Analog signals are distinguished by an infinite possibility of values to represent the infinite possible variations of some transmission characteristic. are characterised by a limited number of representative values. Digital are distinguished by an infinite possibility of values to represent the infinite possible variations of some transmission characteristic. are characterised by a limited number of representative values. Amplitude is the volume, intensity, or loudness of a signal. In a sine wave representation of a signal, it is the distance from the X axis.
Frequency is the volume, intensity, or loudness of a signal.
In a sine wave representation of a signal, it is the distance from the X axis. Phase is the volume, intensity, or loudness of a signal. In a sine wave representation of a signal, it is the distance from the X axis. The characteristic of a periodic signal that describes the instantaneous position relative to the beginning of a cycle. Controlling the volume, intensity, or loudness of a signal.
