variations in the amplitude of a carrier wave.
ASK uses a finite number of amplitudes, each assigned a unique pattern of binary digits. Usually,
each amplitude encodes an equal number of bits.
FSK
Frequency-shift keying.is a frequency modulation scheme in which digital information is
transmitted through discrete frequency
changes of a carrier wave.[1] The simplest FSK is binary FSK (BFSK).
BFSK uses a pair of discrete frequencies to transmit binary (0s and 1s) information.
[2] With this scheme, the "1" is called the mark frequency and the "0" is called the space frequency
PSK
PSK phase shift keying.is a digital modulation scheme that conveys data by changing, or
modulating, the phase of a reference signal (the carrier wave).
Any digital modulation scheme uses a finite number of distinct signals to represent digital data.
PSK uses a finite number of phases, each assigned a unique pattern of binary digits.
BPSK
Binary Phase Shift Keying.BPSK (also sometimes called PRK, phase reversal keying, or 2PSK) is
the simplest form of phase shift keying (PSK).
It uses two phases which are separated by 180°.
Signal Wave
In <modulation mode>, the signal wave is used to modulate the carrier signal waveform. It's
source can ether be internal or be external.
The Shape of the Signal Wave should be choosed, when the source is inernal. Except Noise and
Dc, Other wave can be Signal Wave.
Carrier
It is a waveform (usually sinusoidal) or sine wave that is modulated (modified) with an input signal
for the purpose of conveying information.[1] This carrier wave is usually a much higher frequency
than the input signal
Modulation Depth
It indicates how much the modulation varies around its "original" level. It's range is from 0% to
120%.
Frequency Deviation
It is used in FM radio to describe the maximum instantaneous difference between an FM
