Study Notes
Analog Processing
- Analog processing involves differentiation, integration, filtering, and amplification
- Implemented using passive or active electronic circuitry consisting of resistors, capacitors, and inductors
- Analog processing is used to extract useful signals from received signals
Received Signal and Noise
- Received signal r(t) consists of useful signal s(t) and unwanted noise n(t): r(t) = s(t) + n(t)
- Main function at the receiver is to extract useful signal s(t) or obtain its estimate from received signal r(t)
Analog Low Pass Filter (LPF)
- Analog LPF is used to reduce high-frequency noise and extract useful signal component
- LPF processing generates an estimate of useful signal ŝ(t) from received signal r(t)
Limitations of Analog Signal Processing
Accuracy Limitations
- Component tolerances affect accuracy
- Undesired nonlinearities affect accuracy
Limited Repeatability
- Tolerances affect repeatability
- Environmental changes (temperature, vibration) affect repeatability
