Principle

A coil, a capacitor, an ohmic resistance and combinations of these components are investigated for their filter characteristics as a function of frequency. The phase displacement of the filters is determined also as a function of frequency.

Benefits

  • Simple and very clear set-up: only few components required
  • Cost savings: No need for an additional power supply
  • Simplified implementation: all pre-settings already prepared
  • The software controls all devices simultaneously
  • Further experiments in electricity and electronics can be performed with the equipment

Tasks

  • Determination of the ratio of output voltage to input voltage with the
  1. RC/CR network,
  2. RL/LR network,
  3. CL/LC network,
  4. Two CR networks connected in series
  • Determination of the phase displacement with the RC/CR network.
  • Determination of the phase displacement with two CR networks connected in series.
