What are the difference between carrier signal modulating signal modulated signal baseband and passband?
carrier signal- use for the purpose of conveying information. modulating signal- causes variations in some characteristics of carrier signal. modulated signal - carrier signal after altration in its characteristics is called modulated signal. example- if you want to see an object (suppose it is an modulating signal),you need light(light is carrier signal) and when light will reflect on object you will be able to see if (that is modulated signal)
What is correction signal?
correctional signal
Bandwidth of digital signal is infinite?
A digital signal is actually a complex signal. Consider the horizontal part of a digital signal as a component with 0 frequency and the vertical part of the signal as the component of infinite frequency. Also, consider the change from the horizontal to vertical as all the frequencies. Then we can claim that a digital signal is complex signal with frequencies from 0 to infinite.A digital signal is a composite analog signal with an infinite bandwidth.
What is the use of connecting an integrator in delta modulation?
integrator converts the quantised signal to saw tooth signal which then compared with the present signal and error signal is generated,and error signal is quantised and the process continues
Unit step signal is energy or power signal?
The unit step signal is a Power signal. Since when we find the power it comes to 1/2 (i.e finite value). And when we find its energy, we got INFINITY. If a signal has energy as infinity and power as a finite non-zero value, then it is a power signal, not an energy signal.
What is signal verbs?
By using signal verbs, you let readers know the context in which the source's statement should be viewed. For example, if you choose the signal verb say instead of prove, you are reporting that the author makes his statement without any substantial support.
Is it true or faulse I expect you to is an example of a signal statement?
No, "I expect you to" is not a signal statement. A signal statement is a phrase, clause, or sentence that introduces a quotation, paraphrase, or summary. Common signal phrase verbs include the following: argue, assert, claim, comment, confirm, contend, declare, deny, emphasize, illustrate, imply, insist, note, observe, point out, report, respond, say, suggest, think, and write.
Is this a true statement An analog signal consists of individual electrical pulses that represent bits grouped together into bytes?
no. The answer is digital signal.
Statement of sampling theorem?
sampling theorem is used to know about sample signal.
Is it right that a television channel is characterized by frequency of transmitted signal?
Yes, this is a true statement. A TV channel is most often characterized by the frequency of its transmitted signal.
What is a biased statement?
a biased statement is when the answer isn't "the truth" ot fair. It is the opposite of unbiased.
What is the most common word that signals a conditional statement?
A conditional statement is used to show the cause for a reaction. This is an if then type of statement. The most common word that is used to signal a conditional statement is the word if.
When do you use rising and falling intonation for statement?
Rising intonation is used for questions or when seeking confirmation, while falling intonation is used for statements or declarations. Rising intonation at the end of a statement can signal uncertainty or a request for feedback, while falling intonation indicates finality or confidence in the statement being made.
Which elements below the hazard communication standard require on each hazardous chemical label?
The hazard communication standard requires the following elements on each hazardous chemical label: product identifier, signal word, hazard statement(s), precautionary statement(s), and pictogram(s).
Is it true that HDMI cables provide the best quality HD picture because the audio and video connections is in the same cable?
There is no truth in the statement. HDMI is an interface that carries digital audio and video signals. The image quality is dependent entirely on the quality and resolution of the signal that is delivered to the HDMI port by the video source. The HDMI connectors and cable carry that signal to the receiver but the cable does not change it in any way at all. DVI is compatible with HDMI other than the fact that there is no audio carried with the video signal. The video signal is identical to that carried by an HDMI cable and so this alone proves that statement to be false.
What kinds of words often indicate that a statement is an opinion rather than a fact?
Words like "I believe," "I think," "in my opinion," "probably," and "likely" typically indicate that a statement is an opinion rather than a fact. These words signal that the statement is based on personal interpretation or belief rather than objective evidence.
What does . mean at the end of a sentence?
A period (.) at the end of a sentence indicates the end of a statement or sentence in written language. It helps to signal a pause and a completion of a thought.
