Question

Problem Consider the circuit shown in Fig. 1 (a) Qualitatively speaking, what does this circuit do to an ac signal? (b) Make a Bode plot of the amplitude ratio le1leil. (c) Add a Bode plot of the amplitude ratio le2/eil to the graph of part (b). (d) Add a Bode plot of the amplitude ratio jeoleil to the graph of parts (b) and (c). FIGURE 1 Circuit. 160 ? e F 0.1 F 320 ? 5 kS2

Hi, I studied my textbook, and I'm so embressed about something

Cuz, My textbook doesn't have solution about this problum.

I want to know how to solve it.

ps)I'm foregin student

so, write the numbers sharply please.

Have a good Day :)

Answer 1

a) The circuit is a band pass filter. It wotld allow only a group of frequencies to pass and block all other frequencies.

hand calculation has been shown below:

b) Bode plot of e1/ei has been shown below:

c) Bode plot of e2/ei has been shown below:

d) Bode plot of e0/ei has been shown below:
