Original.It changes the sound (pressure waves in the air in the room) into a digital signal.Correction:It changes the sound pressure waves into an ANALOG signal. Any digital signal is the result of feeding the analog mic signal into an analog-to-digital converter, typically in a computer's sound card.Original.An electric guitar doesn't need a microphone because it makes a digital signal.Correction:A simple guitar with magnetic pickups creates an ANALOG signal from the motion of the strings, typically tens to low hundreds of millivolts. If you want a digital signal, you need: 1. Analog-to-digital processing in the guitar itself, or2. Analog-to-digital processing externally, such as a computer sound card.Original.An mp3 recording is a digital signal.
Hi The sound is converted from analogue signal into a digital format and then transmitted with other digitized voice signals across the fibre. Next the digital signal are separated and converted back to analogue signal. regards Philip
The basic elements in digital signal processing are an analog to digital converter, digital signal processor, and digital to analog converter. This process can take an analog input signal, convert it to digital for processing and offer an analog output.
what are the characters of digital signal

An DAC convert digital signal to analog signal i.e Digital to Analog Converter. An ADC convert analog signal to digital signal i.e Analog to Digital Converter.
A 2-channel digital audio signal, or a encoded DTS or Dolby Digital surround sound audio stream.
There are several devices called digital to analog converters for this purpose. 1s and 0s of the digital signal are used to represent the digital signal in analog form.
There are chips that will convert a analog to a digital form. It works on the principle of comparing the input to a reference voltage and outputting the bits [digital] as a value compared to the reference voltage. it can be 4,8,12, of digital data for a 12bits the LSB is 2.4mv.
There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal
