Lecturer talking about digital signal processing. There are some advantages like no additive noise, reliable reproduction and disadvantages like processing time and introduction of quantization noise.

Typical operations: convolution, correlation, digital filtering, transformation, and modulation.

Input filter > ADC > Digital Processor > DAC > Output filter

Low pass filteringto reduce bandwidth and noise which is usually high frequency. The rest of the lecture is basically a rehash of communications systems.
