23. On your new job you have been asked to design a monitoring system for a water treatment process. You have chosen a dissolved-oxygen (DO) detector that operates at a frequency of 30 Hz. You have found that there is a significant source of noise at 5.0 kHz, with roughly the same amplitude as the measurement signal. You decide to minimize (90% reduction) the noise at this wavelength by building an RC filter. Diagram the signals in terms of amplitude...

3.2 Simple Bandpass Filter Design The L-point averaging filter is a lowpass filter. Its passband width is controlled by L, being inversely proportional to L. In fact, you can use the GUI altidemo to view the frequency response for different averagers and measure the passband widths. It is also possible to create a filter whose passband is centered around some frequency other than zero. One simple way to do this is to define the impulse response of an L-point FIR...
