Assignment 5

Identify the reason for a nonsinusoidal signal being distorted when it passes through a filter. -The distortion occurs because harmonics are removed or rejected, leaving a different waveshape. -The distortion occurs because harmonics are synchronized, leaving a different waveshape. -The distortion occurs because the signal is modulated, leaving a different waveshape. -The distortion occurs because harmonics are added in the filter, leaving a different waveshape.

Need help steps would be helpful please and thank you!

You would like to design the lowpass filter above that has a frequency response shown by the Bode plot below.   For a lowpass filter, the passband (the frequency range where signals are passed) is at low frequencies and the stop band (the frequency range where signals are attenuated) is at high frequencies. The corner frequency marks the transition between passband and stopband.  If Rf= 5000Ω you will determine the values of R1 and C  to complete the design. The design is done in steps.  First, determine  the corner frequency (or bandwidth) in rad/sec.  Enter Wb in the box below.   Enter the magnitude of the passband gain, KDC. Recall that a gain in dB is related to the linear gain  by the formula KdB = 20log10|k|.   Enter the value for R1 in ohms . Enter the value for C in μF.

As part of a radio receiver, you are asked to design a simple bandpass filter using a series inductor, capacitor and resistor. The filter needs to pass a centre frequency of f0 = 1089 kHz with a bandwidth of 9 kHz. Do this by finding the capacitor and resistor values together with a 240 uH inductor that will give you the correct centre frequency and bandwidth. Also, calculate the quality factor Q for your filter. Sketch the filter circuit and show all your calculations.
