AM Modulation: Generating an AM signal using a switching modulator circuit and evaluating it in both the time and frequency domain. AM Demodulation: Recovering the original message signal using an ...

This project demonstrates the implementation of Quadrature Phase Shift Keying (QPSK) modulation and demodulation techniques using Python and GNU Radio. Objective: To simulate QPSK signals, focusing on ...

Abstract: As a matter of fact, digital modulation techniques such as Phase Shift Keying (PSK) and Quadrature Amplitude Modulation (QAM) are very important for modern communication systems and are ...

Abstract: This chapter discusses common types of modulation and their variants. It explores the spectral effects of modulation and explains why certain types of modulation are used in differing ...

[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the electronics ...
