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 situations. The ...

Pulse modulation may be subdivided in to two types analog and digital. In analog the indication of sample amplitude is the nearest variable. In digital the information is a code. The pulse position ...

This paper presents an approach for studying the amplitude modulation and demodulation. An algorithm for the laboratory exercise and block diagrams for MATLAB Simulink used in it, are presented. This ...

Developed a user-friendly GUI following a block diagram timeline. Enabled users to choose various modulation and demodulation processes. Processed both real-time and recorded audio signals of ...

[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 ...

SDR, or Software-Defined Radio, is a radio system that uses software to handle tasks like modulation, demodulation, filtering, and encoding. This means it can use common hardware like a computer ...

GFSK modulation block diagram. (2) ... As a result, an improvement has been executed on the physical layer, which is where we dealt with non-coherent GFSK modulation and demodulation; definitely, our ...
