Frequency response of Differentiator v2

01:00:36

Practical differentiator 
F=1 /(2πRC)
When input frequency = F then gain is unity and zero in decibel 
At input frequency less than F then gain in dB is negative. 
At input frequency greater than F then gain in dB is positive. 
At input frequency =0 then gain is very high and almost equal to 2000dB 



Gain = F / (input frequency)
Gain in decibel = 20*log(gain)
