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.
An electric current that is varied to represent information is what?
An electric current that is varied to represent information is called a modulated current. This modulation can take various forms, such as amplitude modulation (AM), frequency modulation (FM), or pulse modulation, and is commonly used in telecommunications to transmit data over long distances efficiently.
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.
How phase lock loop is used as a universal detector for Amplitude Modulation?
I could certainly be wrong, but my recollection is that a phase locked loopis a universal detector for Frequency and Phase modulation, and is quiteinsensitive to Amplitude modulation.
How is pulse amplitude modulation transmitted?
Generally pulse amplitude modulation (PAM) is trasmitted as a series of DC levels and are mostly used in wired trasmissions (DC is not effective wirelessly).
What type of modulation is used to carry the picture portion of a television signal?
Amplitude modulation (AM) is typically used to carry the picture portion of a television signal. The audio portion of the signal is usually frequency-modulated (FM).
Why amplitude modulation is used for video transmission?
IF we use frequency modulation for transmitting video signal this can cause phase shifting .and eyes can percieve this distortion effect easly . and requires more bandwidth to send the signal .Color levels are adjusted by amplitude in TV .So it s more logic to use Amplitude modulation .
In order to send more than one bit at a time during a single phase on a carrier modulation is used?
amplitude modulation is used
How does amplitude modulation transmit ones to zeros?
Amplitude modulations can be used to transmit binary data. Remember AM modulation is done using a single carrier frequency, and increasing or decreasing the amplitude. A high amplitude would be considered a '1', and a low amplitude would be considered a '0' (typically).
What are the two types of wave communication used in broadcasting?
AM and FM AM=Amplitude Modulation FM=Frequency Modulation Hope this helps
Why is intermediate frequency transformer used in amplitude modulation?
used as a adjustable band pass filter...
Why phase modulation is used?
Actually phase modulation was used for the color signal in all analog TV systems.Phase modulation, with some signal preprocessing, was used to indirectly get frequency modulation in many FM transmitters.Certain modems use phase amplitude modulation.etc.
