What type of modulation produces pulses whose duration is proportional to the amplitude of the intelligence signal?
Pulse-Amplitude Modulation
What is the channel bandwidth for 2KHZ signal?
depends on type of modulation and other variables
When modulation frequency is doubled the modulation index is halved and the modulating voltage remains constant the modulation system is?
the modulation system is of FM
In which Analog to analog modulation methods does the peak amplitude?
Frequency modulation Phase modulation
How does quadrature amplitude modulation works?
QAM is a combination of phase modulation & amplitude modulation.
What are the applications of vestigial side band modulation?
Analog tv broadcast systems
What is vestigial side band transmission?
Vestigial sideband (VSB) is a type of amplitude modulation ( AM ) technique (sometimes called VSB-AM ) that encodes data by varying the amplitude of a single carrier frequency . Portions of one of the redundant sidebands are removed to form a vestigial sideband signal - so-called because a vestige of the sideband remains.
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 does vestigial mean and give one example?
The word 'vestigial' means not fully developed in mature animals Vestigial is a small remnant of something that was once much larger.
What is analog modulation?
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)
What is vestigial organ Give an example?
A vestigial organ is an organ that has no beneficial use to an organism. Ex. Tail bone in Humans
What does VSB stand for?
Vestigial SideBand. It is a type of signal modulation (filtering) used in the television communication industry. It is used to help remove signal redundancy in Pulse Amplitude Modulated (PAM) signals. Also look up 8VSB and A-VSB which are variants of VSB.
How many type of modulation?
17
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.
What type of wings does a kiwi bird have?
Vestigial wings.
Which type of anatomic structure are wisdom teeth?
A.Vestigial :)
The values of amplitude modulation index is objective types?
The values of amplitude modulation index is categorized as an objective type.
