In February 2010, iBiquity released a paper on techniques for measuring the quality of IBOC transmissions. A quality-metric known as MER (Modulation Error Ratio) was ...

Amplitude modulation is the transferring of information onto a radio wave by varying the amplitude (intensity) of the radio carrier signal. Figure 1.6 shows that amplitude modulation involves the ...

Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding craving for greater quantities of information. The increased demand has ...

Amplitude modulation (AM) is by far the oldest form of modulation known. The first broadcast stations were AM, but even earlier, CW or continuous-wave signals with Morse code were a form of AM.

There are two radio modulation schemes everyone should know. Amplitude modulation changes the amplitude — or ‘volume’, if you will — of a carrier frequency and turns all radio into channels owned and ...

This chapter introduces techniques to produce digital modulation using synthesizers. There are many types of modulation (ways of encoding data onto a carrier for transmission) in use today. In some ...
