  Digital signal processing allows sounds to be recorded and transmitted in ways not possible through previously used analog technology. Digital signals are now used in a variety of technologies and disciplines including cell phones, music recording equipment and televisions. The digital signal is also greatly benefited from the Internet, which enables users to send digitally produced audio files from one computer to the other.
  
  

You Can Watch Cable

• As of June 2009 analog television broadcasts by full-power television stations ceased in the United States. This means in order to watch cable television in all of its multi-channel glory you need to have equipment with the ability to process a digital signal. This is accomplished with the purchase of a digital television. If you own an analog television set you are required to install a digital converter box. The advantage of the digital signal in regard to television is increased bandwidth and resolution. This is what allows "high-definition" television.
  
  

Versatility of the Signal

• In addition to television broadcasting, digital signals can be used by a variety of electronic devices to control multiple systems. According to Analog's website, digital signals can be received by computers to control security systems, home audio and video devices. The compressed digital signal is able to travel faster from one end to the other, increasing device response times. The signal is also processed more accurately leading to better cell phone call quality and signal integrity. This means fewer dropped calls.
  
  

Ease of Updating

• It is easy to update a digital signal processor through the simple download of new software, according to the website for Radio Electronics. This allows a user to purchase a base model digital processor and continually upgrade its software over time rather than purchasing a new analog receiver whenever new additions are needed. This downloaded software can also enable the digital signal processor to operate in multiple functions including digital music recording and voice recognition.
