Digital signals get corrupted by the noise, or overloa of information Overload of information, static in the air, etc
it is an DAC (Digital to analogue converter
digital
FDM stnds for frequency division multiplexing and it is used only in case of analog signals because analog signals are continuous in nature and the signal have frequency. TDM-stands for time division multiplexing and it is used only in case of digital signals because digital signals are discrete in nature and are in the form of 0 and 1s. and are time dependent.
The digital signals is not converted BACK to analog! it is transmitted in digital form and the receiver is converting it back to analog to drive the speakers. The signal from the microphone is converted from analog to digital with an A/D converter chip, digital signals consist of pulses of different lengths that is switching the transmitter on and off in about the same way as the old Morse code transmissions but at a much higher rate (millions of times higher)
ADC analog digital converter
digital signals have two values. 0 and 1.
Digital signals are measured in bits per second (bps).
The cast of Corrupted Signals - 2009 includes: Dennis Cage as himself Jason Gerbay as himself Allison Herva as herself
Analogue signals are more vulnerable to error than digital signals. See the related question "Why digital signals are more noise free than analogue signals?" for more details.

Analog signals require higher fidelity than digital signals because digital are either on or off while analog are continuous. A small difference in an analog signal is not detectable while it requires a large difference to turn on into off (digital signal). Error correction is easier with digital signals.
Hybrid signals are the combination of both analog and digital signals
