b) When designing a FIR filters, the impulse response of the ideal low-pass filter is usually modified by multiplying it by a windowing function such as the Hamming window which is defined, for an odd number N of samples, by: (2n)-(N-I)-ns(N-1) N-12 wlnl 0.54 + 0.46 cos i What are the advantages of windowing with this function compared 2 with a standard rectangular window? ii) Design a 10th Order Hamming windowed FIR low-pass filter with cut- off frequency at 1000...
Implementing a 3-Band Equaliser
Design and implement a 3-band equaliser using a DSP board or MPLab/CSS. The MATLAB Filter Designer could be used for filter design and graphing subject to the design requirements given below. This is an individual CW 2. Equaliser Primer An n-band equaliser is a device used to correct the frequency response characteristic of a signal processing system. Equalisers can be implemented using digital or analogue filters. The whole bandwidth of the equaliser is divided into n frequency bands, which can...
