The input to an op amp-based low-pass filter with a cutoff frequency of 500 Hz and a passband gain of 8 is 2.2cosωtV.

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.Suppose that vo(t)=Acos(ωt+ϕ)V, where A>0 and −180∘<ϕ≤180∘. Determine the values of A,ω, and ϕ.

c. Find the output voltage when ω=0.1ωc.Suppose that vo(t)=Acos(ωt+ϕ)V, where A>0 and −180∘<ϕ≤180∘. Determine the values of A,ω, and ϕ.

d. Find the output voltage when ω=10ωc.Suppose that vo(t)=Acos(ωt+ϕ)V, where A>0 and −180∘<ϕ≤180∘. Determine the values of A,ω, and ϕ.

A common use of capacitors as a reactive component is in a low-pass or high-pass filter, both of which contain a resistor and a capacitor. A low-pass filter is one that passes through signals with frequencies lower than a particular cutoff frequency and causes attenuation in signals of higher frequency. A high-pass filter is one that passes through signals with frequencies higher than a certain cutoff and causes lower frequencies to attenuate, giving the two configurations their names. The cutoff...
