===== Preparation for the oral short exam =====

For this experiment, you should be able to apply and explain the following concepts:
  - "golden rules" for the negative feedback, idealized operational amplifier
  - Inverting operational amplifier
    - Gain of inverting operational amplifier
    - Sum of currents at inverting input (KCL)
    - Voltage at inverting input relaltive to GND (KVL) 
  - Non-inverting operational amplifier
    - Gain of non-inverting operational amplifier
    - Operational amplifier used as current source (principle of function)
    - Operational amplifier used as low-pass filter, cut-off frequency calculation (Sallen-Key configuration)
