Instantaneous amplitude is the magnitude or strength of a signal at any specific point in time. It measures the maximum distance of a wave from its baseline or center point at a particular moment in time. In telecommunications and signal processing, instantaneous amplitude is important for modulating signals and analyzing waveforms.
The amplitudes simply superimpose so it becomes A + B.
At a given moment in time, instantaneous speed can be thought of as the magnitude of the instantaneous velocity of an object. Instantaneous velocity is the rate of change of an object's position at that specific moment in time.
They are independent quantities. Amplitude decides the intensity ie energy content of the wave and frequency is different right from amplitude. If the maximum amplitude,E, is known then the instantaneous amplitude, e, can be found by e=E*sin(2*pi*f*t) where f is the frequency and t is the time in seconds from the start of the sine wave. Note that the angle in brackets is in radians. -------------------------------------------------------------------- Hi there is no such a term "maximum amplitude". Amplitude itself is the maximum displacement. For a fixed frequency and fixed amplitude, as time passes then the displacement e varies as fractiion of max E. That is all. E is constant and f is another constant. They are not directly related in any way.
Instantaneous velocity is a vector quantity.
I once had a caravan fitted with an instantaneous water heater.
A + b
The amplitudes simply superimpose so it becomes A + B.
the maximum amplitude of carrier wave varied with respect to instantaneous values of message signal is called amplitude modulation
The amplitude is 150; 30
* The term peak amplitude, often shortened to amplitude, is the nonnegative value of the waveform's peak (either positive or negative). * The instantaneous amplitude of is the value of (either positive or negative) at time . * The instantaneous magnitude, or simply magnitude, of is nonnegative and is given by . ALSO Amplitude is the maximum displacement from equilibrium in a sinusoidal wave.Magnitude is just the value of something; typically refering to scalar quantities.

-- the modulation index varies -- the instantaneous deviation varies -- the amplitude of the carrier component varies -- the spectrum of sidebands varies -- the total occupied bandwidth varies
Instantaneous power doesn't have a frequency; it's instantaneous!
The instantaneous voltage at 90 degrees in a sinusoidal waveform is at its peak value, as this angle corresponds to the maximum point of the sine function. Mathematically, if the voltage is represented as ( V(t) = V_{\text{max}} \sin(\omega t + \phi) ), at 90 degrees (or ( \frac{\pi}{2} ) radians), the voltage is ( V(t) = V_{\text{max}} ). Thus, the instantaneous voltage is equal to the maximum amplitude of the waveform.
Amplitude Modulation (AM) and Amplitude Shift Keying (ASK) are both techniques used in communication systems, but they serve different purposes. AM is an analog modulation technique where the amplitude of a carrier wave is varied in proportion to the instantaneous amplitude of the audio signal, typically used in radio broadcasting. In contrast, ASK is a digital modulation scheme where the amplitude of the carrier signal is switched between two levels to represent binary data, making it suitable for digital communication systems. Essentially, AM is used for analog signals, while ASK is used for transmitting digital information.
