Detect the peak of a signal.
If a peak is detected, this block outputs a 1, else it outputs 0's. A separate debug output may be connected, to view the internal estimated mean described below.
- TH factor rise (R)
- Determines when a peak is present. An average of the input signal is calculated (through a single-pole autoregressive filter) and when the value of the input signal goes over threshold_factor_rise*average, we assume we are in the neighborhood of a peak. The block will then find the position of the maximum within a window of look_ahead samples starting at the point where the threshold was crossed upwards.
- Look ahead (R)
- Used when the threshold is found to look if there another peak within this step range.
- Alpha (R)
- One minus the pole of a single-pole autoregressive filter that evaluates the average of the input signal.
