Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

The distribution of content involves the need to adapt digital information to its means of carriage — what we typically call transmission — and to understand that fully, we need to understand the ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

You used to need a couple racks of modulator modules and related gear to accumulate and combine a full complement of TV channel signals that were ready to transmit. Now, you can do most of that with a ...

Mediacom Communications has become the latest cable operator to remove old-world QAM (quadrature amplitude modulation) signals used for linear video off its network, freeing up more wherewithal for ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...

The broadcast industry’s transition between different video delivery methods for streaming TV has led to a massive shift in technology, quality control (QC), and day-to-day operations. During this ...
