Modulation in Massage Therapy refers to the adjustment of various techniques, pressures, or rhythms to enhance the therapeutic effects of the treatment. It allows the therapist to tailor the massage to the client's specific needs, addressing areas of tension or discomfort more effectively. By varying the intensity and style, modulation can help stimulate circulation, promote relaxation, and improve overall body awareness. In essence, it fine-tunes the massage experience, making it more effective and personalized.
The AM power content of the carrier is maximum when the modulation index is zero. At this point, there is no modulation applied to the carrier signal, meaning the entire power is concentrated in the carrier frequency itself. As the modulation index increases, the power is distributed between the carrier and the sidebands, resulting in a decrease in the carrier's power content. Thus, maximum carrier power occurs at zero modulation.
AM imply amplitude modulation of a carrier signal
A: A carrier carry information by modulation either Amplitude or Frequency modulation. Therefore AM and FM RADIO M stand for modulation
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one

In amplitude modulation, modulation depth refers to the ratio of the unmodulated carrier amplitude to the amplitude deviation for which the modulated carrier wave reaches its minimum value. If this minimum value is zero, the modulation depth is 100%.For amplitude modulation,modulation depth = (a-b)/(a+b),wherea is the unmodulated carrier amplitude, andb is the minimum amplitude deviation.The modulation depth ratio is also referred to as the modulation index.

low level amplitude modulation occurs when the carrier signal is first modulated and then amplified,whereas in high level modulation,the carrier signal is first amplified and then is modulated.
Analog modulationIn analog modulation, the modulation is applied continuously in response to the analog information signal.Common analog modulation techniques are:Amplitude modulation (AM) (here the amplitude of the modulated signal is varied) Double-sideband modulation (DSB) Double-sideband modulation with unsuppressed carrier (DSB-WC) (used on the AM radio broadcasting band)Double-sideband suppressed-carrier transmission (DSB-SC)Double-sideband reduced carrier transmission (DSB-RC)Single-sideband modulation (SSB, or SSB-AM), SSB with carrier (SSB-WC)SSB suppressed carrier modulation (SSB-SC)Vestigial sideband modulation (VSB, or VSB-AM)Quadrature amplitude modulation (QAM)Angle modulation Frequency modulation (FM) (here the frequency of the modulated signal is varied)Phase modulation (PM) (here the phase shift of the modulated signal is varied)

No. The carrier "carries" the modulation. The modulation is the intelligence.
Frequency modulation and Phase modulation
angle modulation is called non linear modulation because the information is stored in phase of the carrier signal
In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one
