Abstract [en]

Modulation and demodulation hold dominant positions in communication. Communication quality heavily relies on the performance of the detector. A simple and efficient detector can improve the communication quality and reduce the cost. This thesis reveals the pros and cons of five demodulation methods for Amplitude Modulated (AM) signal and four demodulation methods for Frequency Modulated (FM) signal. Two experimental systems are designed and implemented to finish this task. This thesis provides the researchers an easier reference of demodulation methods with tables listing their pros and cons.
