For a Butterworth filter with N=2 verify that the left half plane poles are located at minus 0.707+j0.707 and at -0.707-j0.707 and that the resulting polynomial matches the second order Butterworth denominator.

Part II: Design of Butterworth Filters Butterworth filters, described in a paper by Stephen Butterworth in 1930, are widely used for CT frequency-selective filtering. Butterworth filters have a simple analytic form and are designed to have a magnitude response that is maximally flat in the passband. In this section, you will use the Laplace transform to design and analyze Butterworth filters in the frequency domain. The textbook has some useful information about Butterworth filters, so check it out to help...
What kind of filter has poles in the imaginary left half plane? (Low pass, high pass, band pass, or band reject). A brief explanation of the transfer function(s) would be great, I am having a hard time understanding the concept behind this. Thank you.
How to choose the bandwidth of the Butterworth, 2 poles filter for ASK modulation? What bandwidth should be if symbol duration is 3 ms?

Using matlab to design H(z) as a 6th order Butterworth filter with bandedges of 0.3 and 0.5. Plot the frequency response of the above filter. Use the quantization function below to quantize the coefficients of the filter to 8 bits, and plot the frequency response. Implement H(z) in cascade form and quantize the coefficients to 8 bits, then plot the frequency response of the resulting filter. Compare the two approaches of implementing a filter and the effects of quantization on...
4. We wish to design a digital bandpass filter from a second-order analog lowpass Butterworth filter prototype using the bilinear transformation. The cutoff frequencies (measured at the half-power points) for the digital filter should lie at ω 5t/12 and ω-7t/12.
