Transmission analysis of a 16-QAM digital channel with constellation diagram

This bandwidth calculator is an essential tool for performing calculations related to common digital modulation schemes such as BPSK, QPSK, and QAM, QAM16 and QAM6, which are widely used in satellite (VSAT), terrestrial broadcasting, as well as ENG, SNG, and BAS applications. It helps with accurate bandwidth estimations by considering critical factors such as Forward … [Read more…]

Frequency modulation vs. phase modulation

1 Comment

Probably any person interested in RF knows the basic concept of frequency (FM) and phase modulation (PM) as the terms are pretty much self self-explanatory. Yet when it comes to the practical implementation, I frequently notice how little the properties of both modulation techniques are actually understood. From my experience, a vast majority falsely believes … [Read more…]
