Voice signals are signals whereas computer signals are?
Voice signals are analog signals, whereas computer signals are digital .
What converts digital signals to analog signals and vice versa?
Digital signal is moreefficientimmune to noiseerror freethan analog signal.
Electric cmarator working on the principal of amplifier and digital sigital signals true or false?
The electric motor does not work on the principle of the amplifier and the digital signals.
What is the purpose of a digital converter?
A digital converter converts the analog signals that are received by your TV to digital signals. Most TV providers only offer digital TV these days, so you only need it if you're still using analog.
Digital formats are descriptions of signals as?
a long string of numbers
What is the alteration called when digital or analog signals are altered to represent binary data?
Modulation
What is the transfer of digital or analog data using digital or analog signals?
The transfer of digital or analog data using digital or analog signals refers to the process of transmitting information from one device to another, either through digital signals or analog signals. Digital signals are electronic signals that represent binary data, while analog signals are continuous signals that represent continuous data. The method of transfer depends on the type of data being transmitted and the technology being used for the transfer. For example, digital data can be transferred using digital signals through a computer network, while analog data can be transferred using analog signals through a telephone line. Regardless of the method used, the goal of the transfer is to accurately transmit the information from one location to another.
What is ofdm symbol?
Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital. Pilot signals and training symbols (preambles) may also be used for time.
What is OFDM training symbol?
Orthogonal frequency-division multiplexing (OFDM) is a method of encoding digital. Pilot signals and training symbols (preambles) may also be used for time.
What is the way in which bit signals are represented on the network medium?
encoding
How are digital signals?
Digital signals are measured in bits per second (bps).
What are the values that digital signals have?
digital signals have two values. 0 and 1.
When a voice signal is converted into a digital signal do the ones and zeros of the digital signals represent letters?
well yes and no yes it Will represents letter but as a function of an ASCII code like digital 41 Will represents the letter A
What are the two types of signals of a computer?
There are dozens of types of signals but two major categories are digital and analogue.Digital signals have descrete voltage levels (if they are binary they represent on and off and may be 3.3V or 0 volts) while analogue signals have continuously varying voltages.
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 DSP processor is used in cell phones?
You need DSP processors to encode/decode the signals, performs channel encoding and source encoding.
What is the name of the device that carries digital signals?
modem is the device that carries digital signals
