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.
Benefits
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
Tasks
Record the frequency response of the output voltage of
a high-pass filter
a low-pass filter
a band-pass filter
a Wien-Robinson bridge
a parallel-T filter, point by point and to display the sweep on the oscilloscope. Investigate the step response of
a differentiating network
an integrating network.
2. Analyse and verify the measurements using the measure analysis software.
