[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 ...

The choice of a modulation method and pulse-shaping scheme depends greatly on the availability of the spectrum, the desired data rate, and the radio channel itself. In turn, the modulation method ...

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.

The LED is connected to a simple analog modulator circuit, which takes an audio signal as its input and sends the data to the light. The solar cell sends its data, with the help of a capacitor ...

In this section we introduce the tools necessary to evaluate and compare various analog voice modulation systems. In order to better understand the factors affecting speech intelligibility, we briefly ...

The MVD DVB-T2 modulator core is delivered for baseband output to be natively connected to AD9789 DAC from Analog Device but can be used in Intermediate Frequency application or in RF application when ...
