6.1 Introduction and objectives
An AC signal will be generated from the motor and optical
interrupter setup as in the previous lab. As the motor speed is varied
the amplitude and frequency of the signal will be measured. A
high- pass filter will then be placed in series with the AC signal. The
amplitude will again be measured as a function of frequency. Next a
low- pass filter will be assembled, and the experiment will be
repeated. The three plots will be plotted on a common set of axis for
your analysis. They will measure the 3 dB point of the various filters.
