Four strain gauges, with specification given below, are available to measure the torque on a cylindrical shaft 4 cm in diameter connecting a motor and load. (a) Draw clearly labelled….

## identify which type or types of lowpass filter have the characteristic described.

Among Butterworth, Chebyshev Type 1, Chebyshev Type 2 and Elliptic filters, identify which type or types of lowpass filter have the characteristic described. (a) Magnitude frequency response in the passband monotonically approaches a slope of zero at zero frequency. (Monotonic means “always moving in thesame direction.” That is, always moving up or always moving down or “not rippling.”) (b) Magnitude frequency response in the stopband monotonically approaches zero as frequency approaches infinity. (c) Fastest transition from passband to stopband for a given filter order. (d) Slowest transition from passband to stopband for a given filter order.
