14–69 Third-Order Butterworth Circuit Show that the circuit in Figure P14–69 produces a third-order Butterworth low-pass filter with a cutoff frequency of

ωC =1=RC and a passband gain of K = 4. Then design a thirdorder Butterworth low-pass filter using the filter in Figure P14–69 with a cutoff frequency of 10 krad/s. Verify your design using Multisim.
