2. You are constructing a system to amplify an input ac signal. Since you are not interested in dc signals, you randomly grab a capacitor out of the bin (it happens to be 15.9 pF) and insert it between your source and the buffer stage of your amplifier system. The output of the buffer stage is open-circuited. C = 15.9 pF R. = 10 n R = 1 MAI>1.V, a. Sketch the Bode magnitude spectrum, (dB) Source Coupling Capacitor Buffer Amplifier versus frequency f (Hz]. Label key values. b. Sketch the Bode phase spectrum, 2 [deg] versus frequency f (Hz). Label key values. c. Sketch the time domain plots v, (t) = 1 cos(2n 1 kHz t) [V] and v. (t) on a common time axis. Plot at least 2 cycles and label key values. %3!
