Passive RC Low Pass Fiter

RC low pass filter: >> R = 500; //ohm >> C = 7e-6; //F >> f=1/(2*pi*R*C) //Hz f = 45.473 For the capacitive low-pass filter with R = 500 Ω and C = 7 µF, the Output should be 70.7% at 45.473 Hz. https://www.allaboutcircuits.com/textbook/alternating-current/chpt-8/low-pass-filters/
