Question

A DAC (digital to analogue converter) can be used for Driving a moving coil meter from a digital thermometer Amplifying radio signals Computing using binary arithmetic Measuring light intensity

Answer 1

A digital to analogue converter can be used in various fields:

*For driving a moving coil meter from a digital thermometer.:Here the input code which is digital in nature is converted into thermometer code .This temperature code then controls the switches.

*For amplifying radio signals:Here it takes Input data in digital form .It then converts it into audio signal in analog form.After that the signal is sent to an amplifier.

*Computing using Binary Arithmetic:DAC is used so that the information of computer (being a binary machine which itself understands each and every task or arithmetic in binary language of 0s and 1s.)can be understood by other devices.

*Measuring light intensity:From a computer here it converts words(in digital domain) from it's parallel port to voltage signals (being in analog domain)
