Methods of Suppressing Unwanted Sidebands Filter System

WebHalf-band filters are lowpass FIR filters with cut-off frequency of one-quarter of sampling frequency f s and odd symmetry about f s /4 [1]*. And it so happens that almost half of the coefficients are zero. The passband and stopband bandwiths are equal, making these filters useful for decimation-by-2 and interpolation-by-2.

WebBandpass Filter Design Example . The matlab code below designs a bandpass filter which passes frequencies between 4 kHz and 6 kHz, allowing transition bands from 3-4 kHz and 6-8 kHz (i.e., the stop-bands are 0-3 kHz and 8-10 kHz, when the sampling rate is 20 kHz). The desired stop-band attenuation is 80 dB, and the pass-band ripple is required to be no … WebMar 8, 2024 · To create a double sideband signal, the carrier signal is multiplied by the audio signal. The Band Pass Filter creates the Single Sideband signal by passing the frequencies from 16300Hz to 19000Hz and rejecting the others (the filter method). This gives a signal with only one sideband (upper) and no carrier.
