What is the basic difference between analog and digital system?
analog signals are continuous but digital signals are discreet. Digital signals have only binary value like zero(off state) or one(on state).
What advantage do digital television signals provide over analog signals?
Digital signals produce a higher quality picture and many programs can be broadcast on a single digital channel, whereas only one program can be broadcast on an analog channel
What are the values that digital signals have?
digital signals have two values. 0 and 1.
How are digital signals?
Digital signals are measured in bits per second (bps).
What converts your voices sound waves to digital signals?
A microphone converts voice sound waves into electrical signals, which are then digitized by an analog-to-digital converter (ADC) to produce digital signals. These digital signals can then be processed and transmitted digitally.
Which of digital signals and analog signals are more vulnerable to error?
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.
Why do digital signal require timing signals?
To measure time between digital signals.
How are digital signals measured?
Digital signals are measured in bits per second (bps).
What is the name of the device that carries digital signals?
modem is the device that carries digital signals
Why is MODEM a necessary component of many data communication system?
because internet that comes down a telephone line are analogue signals and the computer on understands digital signals ( 1 and 0s , Machine code, binary) so the modem translates the analogue signals from the phone line to digital and translates digital signals from the computer to analogue
What converts digital signals into analog signals for use with IDSN?
it is an DAC (Digital to analogue converter
What camera records video as digital signals instead of analog signals?
digital video camera
