Asecond order low pass filter is generally characterized by the following transfer function: �(��) = �' ( (� �)( + � + �' � - + �' ( = 1 (� �)( �' ( + � + 1 ��' - + 1 analyze the relation between the input and output voltage for the circuit in figure 2a (sallen-key second order low-pass filter), and prove that the transfer function, resonant frequency and the quality factor are given by �(��) = 1 1 + ��((�1 + �() − �(�1�(�1�( �' = 1 2�6�1�(�1�( � = 6�1�(�1�( �((�1 + �() design a low pass active filter with 1 khz resonant frequency and a q = 1. because there are multiple parameters for this design, it is good practice to fix the resistor values, and set the capacitors to be integer multiples of one another. for example, let �1 = �( = � and c2 = n c1 where n is an integer, and solve for the value of n that satisfies the q-value. let c1 = 50uf and choose the value of r that satisfy the resonant frequency f0. for the designed filter, draw the absolute of the transfer function |h(ω)| verses frequency.

Given a digital filter with the following numerator and denominator coefficient vectors, respec- tively: num= 0.8831, 1.6234, 2.5118, 1.6234, 0.8831, and den= 1., 1.7342, 2.5277, 1.5502, 0.7998. find the poles and zeros of the filter transfer function. is the filter stable? plot the magnitude and phase of h(ejω) of the filter. hence, determine the type of filter (lp, hp, bp, or notch) it represents. determine the 3-db bandwidth of the filter. if the sampling period is t = 10 µsec, determine the 3-db bandwidth in hz.

Design a first order, low pass active filter with a cutoff frequency of 10 krad/sec +/- 1 krad/sec (you choose the value). determine reasonable values for the resistor and capacitor - elements that you can purchase or find easily. btain the transfer function and show a circuit schematic for your filter. plot the bode plot for your filter using matlab, cascade three of the filters designed in part 1 and repeat the instructions for part 1. now, make corrections to your design to account for the shift in cutoff frequency due to higher order filters. what is the new design and new transfer function to obtain your design cutoff (10 krad/sec) from part 1 with a third order filter? 2. 3. 4. the butterworth filter has several advantagesjover the cascaded 3rd order filter. design and build a third order butterworth filter with the same cutoff frequency. show the transfer function, the circuit schematic for your filter model the filter on matlab. compare with the filter in part 2. give a conclusion/summary of results and a discussion of the differences 5.
