This ebook is quantity III of the sequence DSP for MATLAB™ and LabVIEW™. quantity III covers electronic filter out layout, together with the explicit issues of FIR layout through windowed-ideal-lowpass clear out, FIR highpass, bandpass, and bandstop filter out layout from windowed-ideal lowpass filters, FIR layout utilizing the transition-band-optimized Frequency Sampling strategy (implemented by means of Inverse-DFT or Cosine/Sine Summation Formulas), layout of equiripple FIRs of all typical forms together with Hilbert Transformers and Differentiators through the Remez alternate set of rules, layout of Butterworth, Chebyshev (Types I and II), and Elliptic analog prototype lowpass filters, conversion of analog lowpass prototype filters to highpass, bandpass, and bandstop filters, and conversion of analog filters to electronic filters utilizing the Impulse Invariance and Bilinear rework concepts. definite filter out topologies particular to FIRs also are mentioned, as are basic FIR forms, the brush and relocating usual filters. the whole sequence involves 4 volumes that jointly conceal easy electronic sign processing in a realistic and available demeanour, yet which still comprise all crucial origin arithmetic. because the sequence name implies, the scripts (of which there are greater than two hundred) defined within the textual content and provided in code shape (available through the web at will run on either MATLAB™ and LabVIEW™. desk of Contents: rules of FIR layout / FIR layout options / Classical IIR layout

12 was generated by making the call LVCombFilter(5). 10. , an expression for the frequency of the first null for an additive comb filter having n samples of delay. Use the derived relationship to determine the number of samples of delay needed for an additive comb filter to have its first frequency null at 60 Hz when a signal having a sampling rate of 3000 Hz is convolved with the comb filter. Test your answer. 8. 333), and so forth, suggesting that the normalized frequency of the first null is at 1/T au (this applies to an additive comb filter).

Lyons, Understanding Digital Signal Processing, Second Edition, Prentice-Hall, Upper Saddle River, New Jersey 2004. 11 EXERCISES 1. Write a script that can receive as an input argument an impulse response that conforms to any one of linear phase Types I-IV, correctly identify which type has been input, and compute and display the amplitude and phase responses as well as the magnitude and phase responses. Your script should conform to the syntax below, and it should create plots like that of Fig.

Using M = 1 and Eq. 7) n=0 and the corresponding frequency and phase responses are shown in Fig. 10. Compute and plot the amplitude and phase responses and magnitude and phase responses for the Type IV filter whose impulse response is [1, 1,-1,-1]. 9. CHAPTER 1. 9: (a) Amplitude response of Type II linear phase filter whose impulse response is [1,1,1,1]; (b) Phase response or function of same; (c) Magnitude response of same impulse response; (d) Phase response of same. Using Eq. 11 shows the result.
