-Draw the circuit in Figure 1. Label the part that acts as a filter and the part that acts as a buffer. Let

R_(in)=13k\Omega

and

C=13.6nF

. What is the -3 dB cutoff frequency of the filter? -What's the DC value of

v_(out )

shown in Figure 2 -In Figure 2, let

C_(1)=C_(2)=6.8nF

so that our resistors have reasonable values. Choose the values of resistors 1 through 4 such that you have

V_(1)=6VDC

, quality

Q=5

, unity gain

A_(v)

, and center frequency

f_(0)=900Hz

:

R_(1)=(Q)/(A_(v)\omega _(0)C_(1)) R_(2)=(Q)/((2Q^(2)-A_(v))\omega _(0)C_(1)) R_(3)=(2Q)/(\omega _(0)C_(1))
