Bandpass filter with very high sampling rate

WebFor a given sampling rate ( samples per second ), the Nyquist frequency ( cycles per second) is the frequency whose cycle-length (or period) is twice the interval between samples, thus 0.5 cycle/sample. For example, audio CDs have a sampling rate of 44100 samples/second. At 0.5 cycle/sample, the corresponding Nyquist frequency is 22050 … WebMar 8, 2024 · Filter Characteristics showed in this section was obtained through the procedure explained in the section 2.1 Filter Implementation.
