Formula & Methodology
The transfer function of an RC filter is given by:
H(f) = 1 / (1 + j * f * R * C)
The calculator uses this formula to find the magnitude and phase response of the filter.
Real-World Examples
Example 1: Low-Pass Filter
R = 1 kΩ, C = 100 nF, f = 1 kHz
Magnitude: 0.707, Phase: -45°
Example 2: High-Pass Filter
R = 1 kΩ, C = 100 nF, f = 10 kHz
Magnitude: 1.414, Phase: 45°
Example 3: Band-Pass Filter
R = 1 kΩ, C = 100 nF, f = 10 kHz
Magnitude: 0.707, Phase: 0°
