(Sample)RC Low-pass Filter Design Tool - Result -

Calculated the Transfer Function for the RC Low-pass filter, displayed on a graph, showing Bode diagram, Nyquist diagram, Impulse response and Step response.

CR Filter

Vin(s)→ →Vout(s)
(Sample)Transfer Function:
G(s)= 6250

R = 1.6kΩ
C = 0.1uF

Cut-off frequency

fc = 1000[Hz]

Rise/Fall time of step response

fc = Hz
Stead-state value: %→%

tr = [sec]


p = -994.718394324[Hz]
  |p|= 994.718394324[Hz]
