With the rapid development of digital communication technology, pulse code modulation (PCM), as a basic digital signal processing technology, has been widely used in the fields of speech, image and ...

The "pulse code" in PCM comes from the telephone company's method of sending a pulse or no pulse down the line. Mu-Law signals typically ride on a single 64 Kbps DS0 channel in a T1 line.

Now for the specifics. These may be basic to some, a review for others or an introduction, but a good understanding will help in the design of properly functioning digital audio systems and aid in ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM doe… ...

However, this method's effectiveness is directly tied to the characteristics of the RF signals, such as frequency, power and modulation technique, which impact range, data speed and reliability.
