Circuit Components:

Operational Amplifier $($e$.$g$.,$ LM$741)$Resistors $($R$1,$ R$2,$ R$3,$ R$4)$Capacitors $($C$1,$ C$2)$

Circuit Design:

Use two bandpass filters: one for $1$ kHz and one for $5$ kHz$.$For the $1$ kHz filter:

R$1=15$ k$,$ C$1=10$FR$2=15$ k$$

For the $5$ kHz filter:

R$3=3\mathrm{.}3$ k$,$ C$2=10$FR$4=3\mathrm{.}3$ k$$

Connect the output of each filter to separate output nodes.

PSPICE Setup:

Create a new schematic in PSPICE.Place the operational amplifier and connect it according to the bandpass filter configuration.Connect the resistors and capacitors as specified for both frequency bands.Use a voltage source for input, simulating a signal that contains both $1$ kHz and $5$ kHz components.

Simulation:

Run the simulation and observe the output at each filter's output node.You should see the $1$ kHz signal at one output and the $5$ kHz signal at the other. "After designing the process with pspice, simulation is also conducted to see if the frequency is separated" PSPICE ONLY
