Different types of angles?
obtuse angle reflex angle right
What is a reflex angle and what are the types of reflex angles?
A reflex angle is in between 180o and 360o.
The intersection of the two sides of an angle is called the angles?
the intesection of the two sides of an angle is the angle 's?
What different types of angle?
Oblique and Obtuse
What divides an angle into two equal angles?
It is to bisect the angle into two equal angles.
Why is Angle Modulation called nonlinear modulation?
angle modulation is called non linear modulation because the information is stored in phase of the carrier signal
Why frequency modulation and phase modulation are called angle modulation?
i dont know ans. of this.
What are the two types of wave communication used in broadcasting?
AM and FM AM=Amplitude Modulation FM=Frequency Modulation Hope this helps
What is the difference between frequency modulation and phase modulation?
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.
Why angle modulation is called exponential modulation?
The reason it is called exponential (non-linear) modulation is that the information is encoded within the phase of carrier.
Why is angular modulation called exponential?
It is called angle modulation because it changes the angle of the carrier which is exponential, e.g. sin theta = {(e*j theta + e (-j theta)} / 2
What are the two main types of projection in autocad?
first angle, third angle
The values of amplitude modulation index is objective types?
The values of amplitude modulation index is categorized as an objective type.
Why modualtion is need?
Without modulation, there's be no way to get any information onto a carrier signal. There are several different types of modulation schemes for radio carriers and almost as many different types demodulators to decode the information so that it can be converted into a usable form. For instance, AM (amplitude modulation), FM (frequency modulation), digital modulation, quadrature amplitude, etc.
What is the difference between amplitude shift keying and AM modulation?
Amplitude modulation (AM) is a technique used in electronic communication, most commonly for transmitting information via a http://wiki.answers.com/wiki/Radio http://wiki.answers.com/wiki/Carrier_wave. AM works by varying the strength of the transmitted signal in relation to the information being sent. Angle modulation is a class of http://wiki.answers.com/wiki/Analog_signal http://wiki.answers.com/wiki/Modulation. These techniques are based on altering the http://wiki.answers.com/wiki/Angle or http://wiki.answers.com/wiki/Phase_%28waves%29 of a http://wiki.answers.com/wiki/Sinusoidal http://wiki.answers.com/wiki/Carrier_wave to http://wiki.answers.com/wiki/Transmission_%28telecommunications%29 data. The two main types of angle modulation are: http://wiki.answers.com/wiki/Frequency_modulation (FM) in which the http://wiki.answers.com/wiki/Frequency is varied, http://wiki.answers.com/wiki/Phase_modulation (PM) in which the http://wiki.answers.com/wiki/Phase_%28waves%29 is varied.
Where is delta modulation used?
Adaptive delta modulation is used in audio communication systems to avoid the two drawback of delta modulation.
What are the three types of pulse modulation?
Actually there are four:widthamplitudepositioncodeOf these four pulse code modulation is digital while the other three are analog.
