Examtime Quiz app for Android! Which of the following is the difference equation of the FIR filter of length M, input x(n) and output y(n)? Unity c. Infinity d. Unpredictable. Which of the following condition should the unit sample response of a FIR filter satisfy to have a linear phase? a) True b) False View Answer Explanation: We can express the output sequence as the convolution of the unit sample response h(n) of the system with the input signal. Therefore, digital filtering is one of the basic needs of digital signal processing. It uses a pure javascript implementation of the Parks-McClellan filter design algorithm. 1. This is the Multiple Choice Questions in Active Filters from the book Electronic Devices â Electron Flow Version and Conventional Current Version 8th Edition by Thomas L. Floyd. b) (M-1)/2 when M is even and M/2 when M is odd Consequently, this is not suitable as either a low pass filter or a high pass filter. The simplest design method for FIR filters is impulse response truncation (IRT), but unfortunately it has undesirable frequency-domain characteristics, owing to the Gibbâs phenomenon. 1. Q18. Q5. Join our social networks below and stay updated with latest contests, videos, internships and jobs! This mock test of Test: FIR Filters Design for Electrical Engineering (EE) helps you for every Electrical Engineering (EE) entrance exam. View Answer, 4. They are . b) Frequency sampling method. To practice all areas of Digital Signal Processing, here is complete set of 1000+ Multiple Choice Questions and Answers. 19) In FIR filter design, which among the following parameters is/are separately controlled by using Kaiser window? h(n)= ±h(M-1-n) n=0,1,2…M-1. If you are looking for a reviewer in Electronics Engineering this will definitely help. There are three well known method of design technique for linear phase FIR filter. This set of Digital Signal Processing Multiple Choice Questions & Answers focuses on âDesign of Linear Phase FIR Filters by Frequency Sampling Methodâ. a) True Which of the following condition should the unit sample response of a FIR filter satisfy to have a linear phase? a) Order of filter (M) b) Transition width of main lobe. b) (M-1)/2 when M is odd and M/2 when M is even Consequently, this is not suitable as either a low pass filter or a high pass filter and when h(n)=-h(M-1-n) and M is even, we know that H(0)=0. Design an FIR filter using Hanning window with the following specification (16) 15. If the unit sample response h(n) of the filter is real, complex valued roots need not occur in complex conjugate pairs. Moreover, given these specifications, by increasing the filter order, it is possible to obtain designs that more closely approximate an ideal filter. of this characteristic, recursive filters are also called Infinite Impulse Response or IIR filters. Q17. The system function will be a rational function where in general both the zeros and the poles are at nonzero locations in the z-plane. What is the value of h(M-1/2) if the unit sample response is anti-symmetric? Consequently, the roots of H(z) must occur in reciprocal pairs. If the unit sample response h(n) of the filter is real, complex valued roots need not occur in complex conjugate pairs. The impulse response cannot be directly converted to digital filter transfer function. a) Window design. The length of the impulse a) y(n)=âM+ 1 k= 0 bkx(n+k) b) y(n)=âM+ 1 k= 0 bkx(nâk) c) y(n)=âMâ 1 k= 0 bkx(nâk) d) None of the mentioned For M odd, the center point of the anti-symmetric is n=M-1/2. The windowing method can be used to mitigate the adverse (M-1)/2 when M is odd and M/2 when M is even, (M-1)/2 when M is even and M/2 when M is odd, (M+1)/2 when M is even and M/2 when M is odd, (M+1)/2 when M is odd and M/2 when M is even. The lower and upper limits on the convolution sum reflect the causality and finite duration characteristics of the filter. In the frequency sampling method for FIR filter design, we specify the desired frequency response Hd (Ï) at a set of equally spaced frequencies.
