Discrete-Time Signal Metrics

We are interested in the manipulation and/or the synthesis of audio signals. Because we work with computers, these signals are uniformly sampled, or discretized, in time and/or space. There are various signal characteristics, or signal metrics, that we can make use of to analyze discrete-time signals.

Discrete-Time Signals

Signal Average or Mean

Signal Energy

Signal Power

Signal Variance

Signal Metrics for a Sinusoidal Signal

Decibels (and Logarithms)

Parametrized Exponential Curves
