RC Low-pass filter
1-50 kHz filter
- Design and construct a low-pass RC filter with a break point between 1-50 kHz. The break point is the frequency at which the filter starts to attenuate the AC signal. For a Low pass filter, AC signals with a frequency above 1-50 kHz will start to be attenuated (not passed).
- Now construct the circuit using a non-polar capacitor.
- use a sinusoidal variable frequency oscillator to provide an input voltage to your filter.
- Measure the input and output voltages for at least 8 different frequencies which span the frequency range from 1 Hz to 1 MHz.
- Graph the [math]\displaystyle{ \log \left(\frac{V_{out}}{V_{in}} \right) }[/math] -vs- [math]\displaystyle{ \log (\nu) }[/math]
