a. Signal conditioning circuits are used to process the output
signal from a sensor of a measurement system to be suitable for the
next stage of operation. Discuss any four of these processes.

b. To eliminate short term fluctuation of signals and provide
smoother form of signal, low pass filters are use. Using a passive
low pass RC filer having R= 500Ω, and C=50mF, draw the frequency
response graph using a range of frequencies from ??=0.01rad/s to
??=1000 rad/s.
