Passband Filter Support
Perfect signal processing (filtering) is essential for best decoding results, which are achieved by using the
correct filters in the receiver. Doing so prevents blocking effects from strong nearby signals. However cor-
rectly processed signals may be unavailable, e.g., when a receiver does not offer optimum filters or when
using recorded signals. To overcome these obstacles additional passband filters are included in the
WAVECOM decoders to assist the operator in separating signals within the analyzed frequency spectrum.
In the WAVECOM GUI a passband (PB) tuning bar is placed below the tuning FFT window. If tuning FFT is
not available, as is the case for some modes, the parameters can be set in the Demodulator Menu.
For many modes the parameters PB Center, PB Bandwidth and Center can be individually controlled
(see the table below).
