WebThis study proposes an optical front-end for wideband transceivers based on photonic time compression (PTC) and photonic time stretch (PTS) techniques. The PTC and PTS systems within a transceiver generate and receive wideband RF signals, respectively, which expand the processible signal bandwidth. We present analytical models for characterizing the … WebWhat is an Optical Bandpass Filter? Optical bandpass filters are optical filters that pass one or more specified wavelength band (s) while blocking others. Bandpass filters are referred to by the wavelength range, also known as the passband, which they are designed to transmit.
WebApr 12, 2001 · A broadband and flat-top wavelength response, which is required in WWDM systems, has been realised for the first time by using planar-lightwave-circuit (PLC) technology and lattice-form circuit composition theory. The filter divides the signal every 20 nm with an insertion loss of 1.5 dB and a 1 dB passband width of 16 nm. WebThe two half band filters [7] are used to reduce remain sampling rate reduction to the Nyquist output rate. First half band filter and second half band filter make the frequency response more flat and sharp similar to ideal filter frequency response.

WebFeb 1, 2000 · A new architecture using optical all-pass filters is presented which can realize Butterworth, Chebyshev, and elliptic bandpass filter designs exactly and efficiently using … WebLth-Band – Also called “Nyquist” filters, these filters are a special class of filters used primarily in multirate applications. Their key selling point is that one of every L coefficients is zero–a fact which can be exploited to reduce the number of multiply-accumulate operations required to implement the filter.
