The molybdenum chemical symbol is Mo.
The symbol for "after" is '>'.
there is no symbol for it
The symbol for amplitude typically uses a big 'A'.
The symbol for amplitude is typically represented by the letter "A" in equations and graphs. Amplitude refers to the maximum displacement or distance from the equilibrium position in a wave or oscillation.
The unit for amplitude is the same as the quantity being measured. For example, for sound waves, the unit could be decibels (dB). There is no specific symbol for amplitude as it depends on the context, but it is often represented by "A" or "Α".

The wavelength of a wave can be calculated as the distance between two consecutive points with identical phase. It is represented by the symbol λ and is typically measured in meters. The amplitude of a wave, on the other hand, is the maximum displacement of a particle in the medium from its equilibrium position and is usually measured in meters or units of pressure.
The most commonly used quadrature amplitude modulation (QAM) is 16-QAM. It combines amplitude and phase modulation to transmit data efficiently by encoding four bits per symbol, represented by 16 different signal points on a constellation diagram. This modulation scheme balances bandwidth efficiency and robustness against noise, making it widely used in digital communication systems, including Wi-Fi and digital television.
In 32-QAM (Quadrature Amplitude Modulation), there are 32 different symbols. To determine how many bits each symbol conveys, you can use the formula ( \log_2(N) ), where ( N ) is the number of symbols. Therefore, ( \log_2(32) = 5 ), meaning each symbol in 32-QAM conveys 5 bits of data.
Quadrature Amplitude Modulation (QAM) conserves bandwidth by combining both amplitude and phase modulation to transmit multiple bits of data per symbol. By varying the amplitude of two carrier waves that are out of phase with each other, QAM can represent multiple symbols in a single transmission, effectively increasing the data rate without requiring additional bandwidth. This allows for more efficient use of available spectrum, accommodating higher data rates in limited frequency channels.
in qpsk we are using phases for representation of messages while in qam we hav amplitude levels. in qpsk 2 bits per symbol is used with four different phases. in qam depanding on type i.e 16 qam,64 qam,256 qam how many amplitude levels to be used accordingly i.e 16,64,256. sonender kumar

The symbol for component testing using a cathode ray oscilloscope (CRO) is typically a sine wave, representing a signal being tested. The CRO displays the waveform of the signal, allowing for analysis of its amplitude, frequency, and phase characteristics. By examining how the signal behaves on the CRO screen, technicians can determine the health and functionality of the component being tested.
The more energy a wave carries the greater it's frequency is.E=hvE - energyh - Planck's constantv - frequency (the real symbol is actually the lowercase greek letter "Nu")
