Block Name: PowerEstimate

Code File Location: VisualSim\actor\lib\PowerEstimate

Description

This block estimates the power of the input signal. The output is in decibels, where a power of 1 is 0 dB. This is done by averaging the squares of the input values exponentially "forgetting" old values. The forgettingFactor parameter determines how much averaging is done, and hence how quickly the output responds to changes in the input power.
