RC Low-Pass Filter Characterization

A quick reference for how this profile looks in practice - the cutoff frequency is f_c = 1 / (2πRC), and the full measurement writeup covers the rest. Bold text picks up the accent color.

Method

Three components, one measurement, repeated across five frequencies:

Component	Value	Tolerance
R1	10 kΩ	±1%
C1	100 nF	±5%

Table 1: component values used in the measurement

Measurement Setup

Bench configuration, from source to scope.

Equipment

Function generator, oscilloscope, and the filter board under test.

Calibration

Probes compensated against the scope's built-in reference square wave.

Notes

Ambient temperature logged alongside every run.

def cutoff(r, c):
    return 1 / (2 * 3.14159 * r * c)

Measurements were taken with the scope in AC-coupled mode - see the appendix for the full setup.
