By using 3 order High pass filter and sallen key Low pass filter design a state variable * ? Band stop filter

3. A band-reject filter may be designed by combining a low-pass filter and high-pass filter with a summing amplifier. A 60 Hz signal is to be at least -50dB below the maximum gain value of 0dB as shown below with a two-pole low- pass Butterworth filter and a two-pole high-pass Butterworth filter. What is the bandwidth of the reject filter? IX 60412

Design a single pole  low pass filter with a gain of 10 in the passband and a 3dB frequency of 5kHz.  What is the value of R1?

1. A band-pass filter allows certain frequency bands to pass and can be determined by cut- off frequencies. a. Determine the Fs1, Fp1, Fp2 and Fs2 for the following band-pass filter design in Figure I with sampling frequency of 500Hz, aos 1-0.25x. op1-0.35%, cp2=0.55m and cos2-0.65%.

Given the following filter equation, determine the type of the filter. y[n] = 3x[n] + 2x [n - 1] + 3y[n-1] + 4x[n-2] +5x[n-4] c. Give two advantages of IIR filter compared to FIR filter. IN

Determine type of filter and the cut-off frequency (Fc). High Pass Filter & Fc = 9997.17Hz  Determine the peak voltage at the cut-off frequency (Fc) GIven --> Gain = 0.5, --> Vp = 0.5 x 12 = 6V Find GAIN (Vo/Vi) at  f = .1*Fc gain = 0.0995 Find GAIN (Vo/Vi) at  f = 10*Fc gain = 0.99995 Determine the frequency at which GAIN = .4  (i.e., Vo = .4*Vi) f = 4363.12Hz Draw the  “Frequency Response Plot” in “Log-Log” format

Determine the voltage transfer function of the filter circuit shown below and classify the filter as LP, HP, BP or BS. Clearly explain your reasoning. R₁ R Vin A L voo out
