  9. ECET 350 Inspiring Minds/newtonhelp.com ECET 350 Week 5 Homework For more course tutorials visit www.newtonhelp.com Chapter 9: 19. Design a low pass FIR filter for a 10 kHz sampling, with a pass band edge at 2 kHz, a stop band edge at 3 kHz, and 20 dB stop band attenuation. Find the impulse response and the difference equation for the filter. 26. A high pass filter with a pass band edge frequency of 5.5 kHz must be designed for a 16 kHz sampled system. The stop band attenuation must be at least 40 dB, and the transition width must be no greater than 3.5 kHz. Write the difference equation for the filter.

ECET 350 Inspiring Minds/newtonhelp.com ECET 350 Week 5 iLab Impulse Response Band Pass Filter For more course tutorials visit www.newtonhelp.com Objectives: Design a high-order, FIR band pass using MATLAB and then to implement, test, and analyze the real-time performance of that filter on a target embedded system board. In addition, introduce and compare the numerical formats and processing requirements of digital filters when implemented using floating point versus fixed point mathematics on an embedded system. Results: As per the requirement I designed a filter using MatLab that would meet the required pass band.

Towards this end, we shall learn how to use Fourier transform to obtain Bode plots of systems from time domain data passing through the system. We shall also learn the equivalence of convolution operation in time domain with multiplication operation in frequency domain. Equipment list:
