A classic example of polarization is for waves travelling down a guitar string. The direction of polarization is the direction in which the string is plucked, while the waves travel down the string. Answer and Explanation: The reason sound waves can not be polarized is because they are longitud...
Naturally Occurring Time Offsets in Sine Waves: Some passive components yield a time offset between the voltage across them and the current through them. The voltage across and the current through a resistor are a simple time independent relationship, V/I = R, where R is real and in Ω. ...
Using sine waves to create a square wave. Plot generated by author in Python. What’s amazing about this result is that we have generated a sharp and straight-line plot from smooth sine functions. This shows the true power of the Fourier series to construct any periodic function. ...
A sinusoidal carrier wave of frequencu 1 MHz and amplitude 100 V is amplitude modulated by sinusoidal voltage of frequency 4 kHz producting 50% modulation. The frequencies of lower and upper side band terms are respectively, View Solution ...
Why are the lengths of days in spring and autumn the same?. If the sun does not set, why is it so cold? Why are magnetometer readings taken in the range of 30 - 60 degrees? Why do airplanes normally take off facing the wind? Why AC (Alternating Current) is sin...
The justification for such general statements is that any periodic waveform of an endogenously spiking neuron can be decomposed into a sum of cosine waves. Based on our theoretical proof that any SBF model with noisy cosine oscillators has a Gaussian output function that obeys the scalar property,...
The Lorentz–Fitzgerald contraction appears in the carrier wave (11), while the dilation of time and failure of simultaneity are described by the modulation (12). 9 While this simple structure is obviously unphysical, it can be shown that all standing waves, of whatever form, give rise to...
View Solution Ifωcandωmare angular frequencies of carrier wave and modulating signal respectively, then Band width of amplitude modulated waves is equal to View Solution IfAmandAcare the amplitudes of modulating signal and carrier wave respectively, then modulation index is given by ...
SWA consist of time-varying sinusoidalwaves, or sine waves, that track the centre frequencies ofthe energy bands (formants) of natural speech to reproducethe changes in these frequency peaks across time. SWAare typically composed of three sinusoidal waves thatreproduce the changes in the rst ...
Carefully manipulated sinusoidal voltage (or current) signals are the foundation of the modern wireless age. With this in mind, we can ask ourselves the more relevant questions: Why is electromagnetic radiation the preferred method? Why are other types of wireless communicatio...
