This study module introduces students to operational amplifiers and their applications through a wide range of practical activities.

Typical activities include:

• Determine the action of a zero crossing detector
• Observe the operation of a comparator circuit
• Diagnose a fault in an op-amp comparator circuit
• Make measurements to calculate voltage gain for different values of feedback resistor
• Determine voltage gain for AC inputs
• Determine limits of bandwidth
• Measure the rate of change of output voltage for an integrator circuit
• Diagnose faults in a differential AC amplifier circuit
• Faultfinding operational amplifier circuits
