The shaft shown in Figure P11-4 was designed in Problem 10-19. For the data in row (a) of Table P11-1, and the corresponding diameter of shaft found in Problem 10-19,….
Which method(s) can be done without using any time-domain functions in the process?
We have studied six methods for approximating an analog filter by an IIR digital filter. Impulse Invariant, Step Invariant, Finite Difference, Matched-z, Direct Substitution and Bilinear
(a) Which method(s) can be done without using any time-domain functions in the process?
(b) Which method(s) squeeze(s) the entire continuous-time frequency from zero to infinity into the discrete-time radian-frequency range zero to π.
(c) Which two methods are almost the same, differing only by a time-domain delay?
(d) Which method can design an unstable digital filter while trying to approximate a stable analog filter and, if constrained to only stable designs, restricts the flexibility of the design to only certain types of filters?
