What describes the number of times an analog wave is measured each second during an analog-to-digital conversion?
The sampling rate
What is sampling thearm cocerning the rate of sampling required for analog signal?
It states that for satisfactory representation of the sampled signal the sampling frequency must be atleast equal to twice the highest input freq, which is called nyquist sampling. If its less than twice, undersamplin occurs resulting in distortion.
When converting analog waves to digital waves the higher the sampling rate the more accurately the original wave can be re-created?
true
What is meant by sampling in analog to digital conversion?
while conversion of analog signal to digital signal, we need to convert continuous analog signal to discrete signal. this can be done by dividing the analog signal into specific time slots. this process is known as sampling. there is a condition for sampling that can be given as follows. fs<=2fm
What is the block diagram of Analog to digital converter?
Analog signals are converted into digital signals through the following steps:The analog signal passes through a sample and hold circuit which samples the signal at sampling instants.After sampling, the signal is quantizedAns lastly it is encoded
What does the sampling theorem tell us concerning the rate or sampling required for an analog signal?
You must sample at 2 x the rate of the analog signal (2 x the analog signal frequency).
What is the number of times an analog wave is measured each second during an analog-to-digital conversion?
the Sampling Rate.
What is the sampling rate in Hz?
Sampling rate is a defining characterstic of any digital signal. In other words, it refers to how frequently the analog signal is measured during the sampling process. Compact disks are recorded at a sampling rate of 44.1 kHz.
What describes the number of times an analog wave is measured each second during an analog-to-digital conversion?
The sampling rate
Which of the following describes the number of times an analog wave is measured each second during an analog-to-digital conversion?
Sampling Rate.
What is the advantage of sampling analog signal?
1-What are the advantages of sampling analog signals?2-what are the following terms mean : instantaneous Sampling , Natural Sampling , and Flat-top Sampling ?3- what are the advantages of digital communication over analog communication ?4-Explain the reason for making the sampling frequency greater than or equal to (2B)Hz , where B is the bandwidth of the analog signal

When converting analog waves to digital waves the higher the sampling rate the more accurately the original wave can be re-created?
true
When converting analog waves to a series of numerical values the higher the sampling rate the more accurately the original wave can be recreated?
Yes, that is correct. A higher sampling rate captures more data points per second, resulting in a more accurate representation of the original analog wave. This can improve the fidelity and resolution of the digital audio signal.

Of a sound card is the number of samples taken of an analog sound signal over a period of time?
"The sampling rate of a sound card, which is the number of samples taken of the analog signal over a period of time, is usually expressed as samples (cycles) per second, or hertz (Hz)."(Pg. 436, A+ Guide to Managing and Maintaining Your PC)
Why you are using sampling theorem in communication systems?
sampling is a one type of process use for converting into analog signal to digital signal.
