Hey guys,
I have to design 2nd Order Low Pass Filter with a cutoff frequency 1kHz, in my project but, i don't know if i have found the right circuits yet..
This is the specs of the project:
Implement a 2nd order low pass filter with attenuation ≥ 40 db/decade and has one of the following cut-off frequencies (fc): 1 KHz, 2 KHz, 5 KHz, 10 KHz, 20 KHz or 50 KHz.
and This is the circuits that i have got
1-
L=2.25052 mHy C=11.25259 µfd R= 10 ohm resistor
outputs 1k Hz cuttoff frequency .. is that right ?
2-Butterworth low pass active filter.. which with OpAmp
I wanna know is that right, any of these circuits is right according to my project specs ?
Thank you in advance,
