3.5.6.3 Analogue/Digital Conversion. Flashcards
What does DAC stand for?
Digital to analogue converter.
What is DAC?
A device used to convert digital signals to analogue data.
Describe the principles of operation of a digital to analogue converter (DAC).
A digital signal is converted into an electrical signal which is then passes through an amplifier, creating an analogue signal. Commonly used to convert a digital audio signal to an analogue signal.
Describe the principles of operation of an analogue to digital converter (ADC)
A microphone converts the sound energy into electrical energy. The ADC samples the analogue data at a given frequency, measures the amplitude of the wave at each point and converts it into a binary value using the resolution of each sample
What does ADC mean?
Analogue to digital converter.
