In signal processing, modulation means altering the wave form in some manner. This could include altering one of the three factors of a wave form. These are the amplitude, frequency, and phase.
Amplitude Modulation
J. A. Bett has written: 'Signal processing, modulation and noise'
With DSP you can change, modify, study the properties of signals more easily than analog signal processing. You can do modulation, encryption, decryption, encoding, decoding, multiplexing, comparing etc
Anti Meridian - for times after midnight and before noon.Amplitude Modulation - signal processing and radio transmission (AM radio).
Amplitude Modulation, the method of sending information through radio frequencies.
A(m)/A(c)=0.5 is known as 50% modulation index. where, A(m)=amplitude of message signal A(c)=amplitude of carrier signal

AM imply amplitude modulation of a carrier signal
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
The sine wave symbol is significant in signal processing because it represents a fundamental waveform that can be used to analyze and manipulate various types of signals. Sine waves have specific properties that make them useful for tasks such as filtering, modulation, and frequency analysis in signal processing applications.
amplitude modulation is where we modulate our signal with a carrier signal amplitude changes but frequency remains constant in amplitude modulation
