In: Physics
design and draw the circuit of RL HPF, find the required value of the inductor to get critical Frequency F,r=20KHz, assume the resistor R=(100ohms) and the input Vrms=10V
MULTISIM
RL High Pass Filter is used to filter the high-frequency signal from the low-frequency signal.
Critical frequency:
R=100 ohms
to get 20KHz critical frequency
The signal gets attenuated if it is below 20KHz
At 60Hz
At 5KHz
At 10KHz
At 20KHz
At 25 kHz
Red color indicates the input color and blue color indicates the output
From the above waveform, we can see that the signal gets attenuated more if the frequency of the signal goes below our critical frequency.
