What type of modulation is pulse position modulation and why?
It is a type of Pulse modulation as in PPM the position of pulse of carrier pulse train is varied in accordance with the modulating signal.
What is the advantage of ppm over pwm and Pam?
PPM is a type of pulse modulation where messages are sent using single pulses. PWM is a type of modulation which conforms to the pulse. PAM is a type of modulation in which the information is encoded into a series of pulses.
The values of amplitude modulation index is objective types?
The values of amplitude modulation index is categorized as an objective type.
What type of modulation produces pulses whose duration is proportional to the amplitude of the intelligence signal?
Pulse-Amplitude Modulation
What is high level AM modulation?
High level AM modulation is a type of modulation using class c (90 percent) amplifiers. The system uses medium power tubes or transistors and is bulky.
What is ppm modulation?
pulse position modulation, used in many RC model aircraft controls.
What does AM mean on the radio?
Amplitude Modulation, the method of sending information through radio frequencies.
Which type of modification of radio waves sends signal the farthest?
amplitude modulation
What is the channel bandwidth for 2KHZ signal?
depends on type of modulation and other variables
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.
Why do you use modulation?
MODULATION is a media for transferring information it can come in many forms FM ,AM, PULSES, PAM and so forth.
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
