### Purpose

Momentary mean estimator

### Description

"Momentary mean" is an adaptive estimator and computes the momentary mean of the input signal x.

Its parameter is the

- adaptation time
`tm` for the mean estimator

which uses the same unit as the x-axis of the input signal.

### Tips

`tm` determines the adaptation speed and the robustness of the estimation procedure. Lower values result in higher adaptation speeds but then the estimated mean varies around the true value with high variance. Higher values result in lower adaptation speeds, but then the estimated mean converges more smoothly to the true value in the case of stationary signals.
