Using an RLC circuit to design a band-reject filter, with the two cut off frequencies 40k and 90k Hz. Design the values of R, L, C, quality factor Q, and find the output terminals on the circuit.
Homework Answers
An RLC circuit has a resistor, capacitor and an inductor in series with a voltage source. In the band-reject filter, the output voltage(output terminals) is measured across series inductor and capacitor as shown in the figure below;
So, we can write
The center frequency is kHz
The cutoff frequencies are
Cutoff frequencies are 40kHz and 90kHz
So
Let 
So 
Cut off frequency = 40000+25000 = 65000
Capacitance, 
Quality factor, Q =
