Question

I need help to measure the high frequency cutoff. The circuit below is for HIGH PASS FILTER

I made it but I dont know how to accurately measure the high cutoff as what we did in the lab. in the lab we get 14.35 kHz but when I try in the multisim and varing the freqency as shown in the table below I dont get any change.

Please do it in multisim and explain your answer, thanks.

f	1-kHz	2-kHz	5-kHz	10-kHz	20-kHz	30-kHz	50-kHz	100-kHz	300-kHz
Vo	73.7mV	146mV	347mV	600mV	857mV	956mV	1.04 V	868mV	305mV

Answer 1

STEP1

DESIGN THE CIRCUIT

Step 1 Design the circuit Step 2 we have to calculate the high cutoff frequency of high pass filter which is -3 dB frequency f_H = 1/2 pi R_2 c_1 = 1/2 pi times 10 times 1063 times 0.001 times 10^-6 f_H = 16.2 kHz here gain = -3 dB Since we are dealing in gain in dB So we will use Bode plotter tool of multiuse Here cutoff frequency is 15.71Khz NOTE;- There may be + 5% or -5% variation in gain can be possible from calculated ,simulated and experimented . Reason: - As we are dealing in analog circuits ,So there is high chances of introduction of different kind of noises due to temperature and other factors.

STEP 2

we have to calculate the high cutoff frequency of high pass filter

which is -3 dB frequency

Since we are dealing in gain in dB So we will use Bode plotter tool of multisim

Here cutoff frequency is 15.71Khz

NOTE ;- There may be +5% or -5% variation in gain can be possible from calculated ,simulated and experimented .

Reason :- As we are dealing in analog circuits ,So there is high chances of introduction of different kind of noises due to temperature and other factors.
