Method 1:
Give the circuit a square wave signal, and use an oscilloscope to observe the square wave signal, from which you can obtain certain frequency response characteristics.
 

 

Method 2:
Use a signal source to give the circuit a frequency sweep signal, the signal type is a sine wave, and the frequency sweep range is the frequency domain range you want to see. Adjust the timing to 200ms on the oscilloscope, and you can see something.
