The low pass filter only allows low frequency signals from 0Hz to its cut-off frequency, ƒc point to pass while blocking those any higher.
To create a low pass filter with a frequency cutoff of 1000 Hz, we can use the following formula to determine our capacitor value based on the chosen resistance.
R=47
fc=1000
fc = 1/(2πRC)
C=1/(2πRFc) = 1/(2π*1000*47) = 3.3 μF
