Name: IIR Filtering: Filter-Design Exercise in MATLAB
ID: m13799
Language: English (en)
Summary: You will derive the transfer function of a second-order, Direct Form II, infinite impulse response (IIR) filter. Then you will create a fourth-order IIR filter, plot its frequency response, and decompose the fourth-order filter into two second-order sections, choosing an appropriate gain for each stage to prevent overflow.
Subject: Science and Technology
Keywords: conv, difference equation, direct form II, DSP, ellip, elliptic low-pass filter, freqz, gain factor, IIR, impulse response, infinite impulse response, linear time-invariant, LTI, notch filter, overflow, poles, zeros
