581K What is the frequency of a wave? Learn the wave parameters including amplitude, frequency, and period. Understand the differences between these wave parameters. Related to this QuestionWhat does the velocity of a wave measure? What would be the speed of a wave that has a wavelength of...
QAM (quadrature amplitude modulation) is a method of combining two amplitudemodulation(AM) signals into a single channel. This modulation scheme helps double the channel's effectivebandwidth. QAM is also used with pulse AM in digital systems, such aswireless communications. How does QAM work? QAM...
How does the Doppler effect manifest itself in the light? What are radiant waves? What is the standard piece of apparatus used to measure distance in the laboratory? What is a stroboscope? What is Venturi-meter? What are the precautions you should observe while doing the experiment with the ...
1. Definition of Amplitude: Amplitude refers to the maximum displacement of a particle from its mean (or rest) position in a sound wave. 2. Understanding Mean Position: The mean position is the equilibrium position where the particles of the medium would rest if there were no sound wave pa...
Often, the interest in phases has more to do with comparing two waves than it does with the individual wave. Phase difference, also calledphase angle, is a measure in degrees of how much one wave leads another wave or lags behind that wave. ...
Electric power is measured in watts (W), kilowatts (kW), and megawatts (MW). Energy is the amount of water that comes through the hose over a period of time. That’s why your electric bill will be given in kilowatt-hours (kWh). Why do we measure power? Measuring voltage and ...
If you produce one sound wave with the same amplitude but opposite phase, you get something called an antiphase. Added together, the two sounds cancel each other out. The result? Silence (or near enough). Clever, eh? You can read a more detailed explanation on our page about how active ...
If the calibration isn’t correct, you might see two sine waves in phase with the amplitude of CHA different from CHB. Recalibrate if there is a significant voltage difference. Measure the phase angle between two generated waveforms: Be sure that CA V/Div and CB V/Div are both still ...
A measure of the total energy or intensity. The magnitude of the earthquake was 7.1 on the Richter scale. 2 Amplitude Pertains to wave phenomena. Light waves of higher amplitude appear brighter to the eye. 4 Magnitude Helps in categorizing and comparing events. The magnitudes of stars are comp...
Amplitude The measure of something's size, especially in terms of width or breadth; largeness, magnitude. Altitude Height of rank or excellence; superiority. Amplitude (mathematics) The maximum absolute value of the vertical component of a curve or function, especially one that is periodic. Altitu...
