Study Notes
Computer Controlled Systems and PLCs - Lecture Summary
- Lecture 1 on Computer Controlled Systems by Dr. Mohammed M Abozahhad on 16/10/2023
- Distinctions between embedded systems and PLCs: All PLCs are embedded systems, but not vice versa. PLCs are more easily reprogrammable and less complex to program than embedded systems.
- PLC applications: Car wash automation, material handling, laser cutting, elevators, and pouch filling machines.
- Equalization in communication systems: Goal is to remove time-domain inter-symbol interference and amplify high-frequency content.
- Compensating for low-pass filtering: High-pass filter can help compensate for low-pass filtering in a communication channel.
- Equalizer implementation: RX DFE implementation pre-distorts the transmitted pulse to invert channel distortion.
- Setting coefficients of a TX FIR filter: Least Mean Squares (LMS) Algorithm is commonly used to set the coefficients of a TX FIR filter.
- Limitation of a TX FIR filter: It attenuates low-frequency content.
