Using Digital Methods
Discuss the concepts of multiplexing and demultiplexing.
Step by step
Solved in 2 steps
- Mixing together different signals into a single signal is called Separating out signals that have been mixed together is called signal untangling demultiplexing signal splicing multiplexingFourier Transform for x(t) = 10 rect (t/7) is 10 sinc(10 f) 7 sinc(10 f) 70 sinc(7 f) 10 sinc(7 f) 10 sinc(70 f) LPF filter is the first stage in digital communication and remove high frequency remove low frequency attenuate analog signal amplified analog signal remove all frequenciesDigitization Briefly explain in your own words the concepts of sampling, sampling frequency, and quantization in the context of digitizing an analog signal.
- What is the benefit of multiplexing?Explain what multiplexing and demultiplexing are used for.Ideal sampling is used Delta signal for sampling Sine wave signal for sampling Triangular signal for sampling Cosine wave signal for sampling Pulse signal for sampling One of advantages of digital communication is Use high frequencies Simple circuit design No synchronous issues Low bandwidth Cheap digital circuit
