Uses 2nd order allpass filters for the 2x upsampling, followed by a notch filter just above Nyquist. -Uses 2nd order allpass filters for the 2x upsampling, followed by a notch filter just above Nyquist.

This program was developed to help students better understand the connections between Bode, Nyquist, Nichols, Gain, Root Locus, and Time Response plots. This includes straight-line approximations and even steps necessary to constructing a root locus.
