WebOur Tunable Fabry-Perot Filters are the only fiber design able to scan reliably to 40KHz scan rates. Fabry-Perot sensors and filters are essential assets in any optical sensing … WebThe filter will have linear phase; it will be Type I if numtaps is odd and Type II if numtaps is even. Type II filters always have zero response at the Nyquist frequency, so a ValueError exception is raised if firwin is called with numtaps even and having a passband whose right end is at the Nyquist frequency. Parameters: numtapsint
