any signal, be it be noise is composed of sinusoids...so when one differentiates sinWt with respect to time it becomes WcosWt ...hence the signal gets multiplied by W..

What are the disadvantage of ultrasonic wave communicaton?

Communication is at speed of sound. Signal attenuation. Noise of signal travelling through air.


Why do you use delta-sigma modulation instead of delta modulation?

Delta sigma modulation achieves "noise shaping" that essentially high-pass filters the quantization noise. This reduces the noise power in the baseband so that oversampling can access more bits of useful signal resolution than would be possible in the presence of the unfiltered noise.

What is gain in electronics?

In electronics, gain measures how much bigger an amplifier's signal output (or the output of some other circuit) is relative to its signal input. The word "gain" can be ambiguous; "a gain of seven" may imply that either the voltage, current, or the power is increased by a factor of seven. For example, When listening to music on the radio, a series of stages converts and amplifies (with a some gain at each stage) an almost imperceptible over-the-air signal, step by step, into a rhythm coming out your speakers as loud as you want it.


What is transistor noise?

http://www.vias.org/transistor_basics/transistor_basics_04_05_03.html The minimum signal that can be applied to a transistor is limited by the internal noise generated by the transistor. Since the transistor does not require cathode heating (one of the major noise sources in the vacuum tubes), it is inherently capable of operating at lower noise levels than its vacuum tube brother. At present, the junction transistor is equal to the vacuum tube, insofar as its noise characteristics are concerned. The noise level of the point-contact types is between 15 and 30 db higher. see the website, there is a lot more. do more research for certainty.

A what amplifies the communication from a signal molecule?

A receptor amplifies the communication from a signal molecule by triggering a series of intracellular signaling events upon binding to the molecule. This signal amplification allows for the coordination of complex cellular responses to the original signal molecule.


What do engineers use the signal to noise ratio for?

Signal to noise ratio is a measure of signal strength to the background noise. Engineers use the signal to noise ratio to improve digital signal processing.
