Designa low-pass filter that reduces magnitude of H(jw) to 0.4
for the signal with 10(X+4)Hz.
a)Use 10 Ω resistor and calculate the value of the inductance of
the filter. Calculate the cutoff frequency of the filter
.b)Design another filter for the same purpose by using the same resistorcombined with a capacitor.Find the value of the capacitance.Find the magnitudes of H(jw) for 2Hz and 200 Hz frequencies and sketch the frequency response graph of the filter
c)(20+Y)Ωresistive loadis connected across the output terminals of the second filter. Find the new cutoff frequency (in hertz)of the loaded filter.Explain the effect of connecting load by considering the new cutoff frequency. Derive an expression for the new transfer function for the loaded cases.
