PPT-(4) Filters 1 Frequency Response

If the quantity we are trying to measure is continually changing will we be able to follow it If the changes speed up at what point will we fail to keep up with the changes This is the cutoff frequency. Filters in this class are specified by two parameters the cutoff frequency and the filter order The frequency response of these filters is monotonic and the sharpness of the transition from the passband to the stop band is dictated by the filter ord Filters, frequency response, time domain connection, bode plots, resonant circuits..
