Figure P1.66 shows a signal source connected to the input
Chapter 1, Problem 1.66(choose chapter or problem)
Figure P1.66 shows a signal source connected to the input of an amplifier. Here Rs is the source resistance, and Ri and Ci are the input resistance and input capacitance, respectively, of the amplifier. Derive an expression for and show that it is of the low-pass STC type. Find the 3-dB frequency for the case Rs = 20 k, Ri = 80 k, and Ci = 5 pF.
