We can pull all that together into an educational model for two SDRs talking to each other, but it’s going to require two parts: modulation and demodulation. Guess what?

Frequency Modulation (FM) sounds simple at first, but understanding the electronics behind modulation and demodulation of an FM signal can be confusing.

There are many differences between information communication and audio algorithms. Information communication primarily ...

There are many different varieties of modulation but they all fall into three basic categories, namely amplitude modulation, frequency modulation and phase modulation, although frequency and phase ...

DiBcom and TeamCast have teamed up to provide programmable mobile TV solutions that can be configured similarly to meet the modulation and demodulation requirements of current broadcast standards, ...

Figure 2: Spread spectrum modulation and demodulation using PSK for primary modulation. Receiver If despreading is applied to the received diffuse wave, it returns to the PSK or FSK modulated wave ...
