8.1). Set the signal generator for square wave ±4V, frequency 0.2 Hz approximately.
Replaces the input signal (setpoint) with this square wave signal.
8.2). Choose gain a K that gives an underdamped response.
8.3). Record the output signal using Digital Storage Scope and determine the following
values: max C (maximum value), final C (final value), p T (peak time), and ss e (see
Figure 3).
8.4). Analyse all results and determine the system transfer function.
