ow-pass filter

The input to the low-pass filter designed in Problem 15.3 is 3.5 cos ωt V.

a) Suppose the power supplies are ±VCC. What is the smallest value of VCC that will still cause the op amp to operate in its linear region?

b) Find the output voltage when ω = ωC.

c) Find the output voltage when ω = 0.125ωC.

d) Find the output voltage when ω = 8ωC.

Problem 15.3

Design an op amp-based low-pass filter with a cutoff frequency of 2500 Hz and a pass band gain of 5 using a 10 nF capacitor.

a) Draw your circuit, labeling the component values and output voltage.

b) If the value of the feedback resistor in the filter is changed but the value of the resistor in the forward path is unchanged, what characteristic of the filter is changed?
