RC filters
Resistor-Capacitor (RC) circuits serve as filters for frequencies. The frequency response of the most commonly used RC filters is recorded by point-by-point measurements as well as the frequency sweep method, and displayed on the oscilloscope. The results are plotted and verified using the measure analysis software.
- Investigate several types of frequency filters
- High-resistance inputs of the difference amplifier allow measurements without influencing the electrical behaviour of the circuit
- Easy frequency setting thanks to digital function generator
