PURPOSE: To demonstrate differentiation and integration using an RC circuit.
DESCRIPTION: The resistance and capacitance from the packaged RLC resonant circuit experiment are used to demonstrate differentiation and integration by an RC circuit. Shown below are the circuits for differentiation (at left) and integration (at right). The photograph above shows a triangular wave (top trace) and its derivative, a square wave (bottom trace). Setting the capacitance at full scale (about 300 picofarads) and the resistance at half scale (about 50 kilohms), frequencies of 500 Hz for differentiation and 100 kHz for integration can be conveniently used.
SUGGESTIONS: None.
EQUIPMENT: RLC circuit demonstrator with Wavetek generator and dual trace oscilloscope.
SETUP TIME: 5 min.
