hello
trying to analyze a circuit and couldn't understand this part of the circuit, in the description of the circuit it says its an active low pass filter. can anyone help me with analyzing this circuit? THANKS
OK, first I will do an analysis of the circuit using LaPlace transforms, and then I will check the results with a CAD program.
The four simultaneous equations for the frequency analysis are as follows:
The Bode plot of vout/vin is:
And, the Bode plot of the CAD program is:
Notice that the x-axis of the first Bode plot in radians and the x-axis of the CAD program is in hertz. Ask if you have any questions of how the solution was derived.
