What is depth of modulation?
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.

What is the minimum number of samples that pulse amplitude modulation needs to take per second to reproduce?
8000 Hz
Which modulation scheme requires the least minimum bandwidth?
Suppressed carrier single sideband amplitude modulation - SCSSBAM.
Which analog modulation scheme requires minimum transmitted power and minimum channel bandwidth?
ssb modulation scheme
What is positive and negative modulation?
in order to transmit the video signal amplitude modulation is used. the composite video signal has distinct polarity of black and white levels in the picture.1.positive modulation :- in this type of modulation, increase of brightness toward white causes increase in carrier amplitude peak white has 100% modulation while black and sync level have lower and minimum modulation respectively2.negative modulation :-in this type of modulation,the sync tip level are at 100%.blanking level correspond to black is at 75%and increase in brightness toward white causes decrease in carrier amplitudeNegative modulation is preferred over positive modulation because impulse interference is difficult to deal with and random increase in signal is similar to existing sync pulse.these interference result in generation of black spot and white blobs.
The lowest point on a wave is the wave?
Minimum? Distance from equilibrium to minimum is the amplitude...
Which modulation technique is used in gsm?
GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.
Why you called minimum shift keying as minimum?
Because as it is equivalent to FSK with lowest modulation index "h" , such that the signal elements are still orthogonal,
How do you find amplitude in trigonometry?
The amplitude of a sine (or cosine) curve is the difference between the maximum and minimum values of the curve, measured over a whole cycle.
What does amplitude represent in a ferris wheel?
amplitude of a Ferris wheel represents the distance from the axis of rotation of the wheel to the maximum or minimum height of the wheel above the ground.
What is the relation between carrier frequency and modulating signal?
If the modulating system is AM (Amplitude Modulation) then the amplitude of the carrier wave changes with the amplitude of the modulation. On a specrum analyser that shows up as frequency sidebands. If the frequency of the carrier waves depends on the amplitude of the modulating signal that is called FM (frequency modulation). On a spectrum analyser that shows up as sidebands also.
