What is the simplest band pass filter?
The simplest band pass filter is a series orparallel LC tuned circuit. Figure 1(a) shows theresonant circuit that is connected to a source of Figure 1(a). The resonant circuit connected to asource of resistance of Rs. resistance of Rs. Using the voltage division rule,it can be shown that
What is a bandpass FIR filter in MATLAB?
Bandpass FIR ?lters can be used to extract the information encoded in the wave-forms. The goal of this lab is to design and implement several bandpass FIR ?lters in MATLAB, and use the?ltered outputs to determine automatically which note is being played.
Why does each octave of a filter have a different length?
Each ?lter has a differentlength and a different center frequency. The lengths have to be different because the bandwidths ofthe octaves are different. In fact, the bandwidth of each octave is twice that of the next lower octave. For each ?lter, determine the lengthLthat is required to get the correct bandwidth.
