Voice signals are signals whereas computer signals are?
Voice signals are analog signals, whereas computer signals are digital .
What is the need for convolution in digital signal processing?
If we need to add two signals in time domain, we perform convolution. A better way, is to convert the two signals from time domain to frequency domain. This can be achieved by FAST FOURIER TRANFORM. Once both the signals have been converted to frequency domain, they can simply be multiplied. Since Convolution in time domain is similar to multiplying in Frequency domain. Once both the signals have been multiplied, they can be converted back to time domain by Inverse Fourier Transform method. Thus achieving accurate results.
What are the elementary signals in electronics?
What are elementary signals and name them
Can you apply time delay for traffic signals?
Traffic signals in the UK already have a time delay built-in. From the time the signal goes red, there is a short delay before the opposing signal changes to amber, then green. This is to allow any traffic already moving, or waiting in the junction, to clear the 'danger' area before other traffic starts to move.
How are analog signals transmitted-?
Analog signals are transmitted as electrical waves.
What signals the passage of time in a passage?
transitional words
What is Time signals in writing essays?
Time signals are words or phrases that indicate the sequence of events or ideas in an essay. They help readers understand the chronological order of information being presented. Some common time signals include "first," "next," "then," and "finally."
How do global positioning systems work?
They calculate the time difference for signals from different satellites to reach the receiver.
What is sequence signals?
sequence signals are signals that are used to arrange events in proper order...! for example..the teacher is in a wrong grammar..!
What signals are likely to be aperiodic?
Signals that are likely to be aperiodic include impulse functions, noise signals, and random signals. These signals do not exhibit a repeated or periodic pattern over time.
What are binary options signals?
Binary Options Signals display the volatile underlying asset & forecast the direction and expiration time in order to make a successful trade. Signals are valid to place a trade in a short window of time after delivery - the Trader is advised to act within the first 5 minutesfollowing the appearance of the signal to guarantee the best possible outcome.

Why do digital signal require timing signals?
To measure time between digital signals.
Why there is a need to convert time domain signals to frequency domain signals?
to find their ESD and PSD
Differences between energy and power signals?
Energy signals have finite energy over time, meaning that the total energy is finite. Power signals have finite power over time, meaning that the average power is finite. Energy signals have zero power; power signals have infinite energy.
How do you record the maximum height of a weather balloon?
Flight time of radio signals, triangulation. GPS signals.
Why FDM is for analog signals and TDM is for digital signals?
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.
Why are the traffic signals always in order?
Are you sure that that's order and not just a strange case of disorder?
