The NXP TDA5051A is a complete Amplitude Shift Keying (ASK) modem for transmitting and receiving digital signals on standard power line or any two-wire AC or DC network. It is a cost-effective ...

When you’re looking to add some wireless functionality to a project, there are no shortage of options. You really don’t need to know much of the technical details to make use of the more ...

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 ...

Digital information often must travel through analog channels in applications like satellite communication, digital cellular phones, digital microwave communication, and others. This transmission is ...

Radio Control /Remote Control and ASK (Amplitude Shift Keying) /OOK (On /Off Keying) have been around for some time, but there is limited coherent information on the subject and the associated ...

In modern communication systems, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as air ...

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 ...

[Dale Cook] has cats, and as he readily admits, cats are jerks. We’d use stronger language than that, but either way it became a significant impediment to making progress with an RFID-based sensor to ...

Changing the amplitude of a radio wave. A higher wave is interpreted as a 1 and a normal wave is interpreted as a zero. By changing the wave, the RFID tag can communicate a string of binary digits to ...
