What is light modulation?
Light modulation refers to the process of varying a light signal's properties, such as its intensity, frequency, or phase, to encode information. This technique is widely used in telecommunications, such as in fiber optic communication, where data is transmitted over long distances. Modulation allows for efficient transmission and improved signal quality by adapting the light signal to different conditions and requirements. Common methods of light modulation include amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM).
Which modulation technique is used in gsm?
GSM uses GMSK modulation scheme. GPRS also uses GMSK modulation scheme. EDGE and UMTS uses 8-PSK.

What is amplitde modulation know was today?
Amplitude modulation (AM) is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. In AM, the amplitude of the carrier wave is varied in proportion to the waveform being sent, such as audio signals. This method allows for the broadcasting of audio content over long distances, though it is more susceptible to noise and interference compared to other modulation methods like frequency modulation (FM). Today, AM is still used for radio broadcasting and in aviation communications, although digital modulation techniques have gained popularity.
What uses complex signal?
Complex signals are commonly used in various fields, including telecommunications, audio processing, and radar systems. In telecommunications, they enable efficient data transmission and modulation techniques, such as Quadrature Amplitude Modulation (QAM). Additionally, in audio processing, complex signals facilitate the representation of sound waves, allowing for advanced effects and manipulation. In radar systems, complex signals are essential for target detection and tracking through the analysis of phase and amplitude information.
What is function of amplitude modulation?
Amplitude modulation (AM) is a method used in telecommunications to vary the strength (amplitude) of a carrier signal in proportion to the waveform being sent. This modulation technique allows the transmission of audio or data signals through changes in the amplitude of the carrier signal. AM is commonly used in broadcast radio to carry audio signals.

AM and FM

What is the difference between the AM modulation and ASK modulation?
This is hard to explain. AM means amplitude modulation, while ASK is amplitude-shift keying. AM is usually analog as it is modulated based on the strength of the signal, though you can use it to send a digital signal. ASK represents digital data as variations in the amplitude of a carrier wave. Any digital modulation technique will represent the data using a finite number of different signals. While AM is used mostly for radio and television, ASK is used for telegraph signals, transmission across telecommunications equipment, and fiber optics.
What refers to waves continuously varying in strength and quality?
This refers to the concept of modulation, where a carrier wave's strength or characteristics are modified to convey information. Modulation techniques include amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM). These techniques are commonly used in telecommunications for transmitting signals over long distances.
