What is a carrier reinsertion oscillator?
A carrier reinsertion oscillator is an electronic circuit used in a radio receiver that is designed to receive single side band carried suppressed radio transmissions. As suggested by the name, in a single side band carried suppressed signal, the carrier signal is suppressed (not transmitted) to save power and/or bandwidth. Before the single side band carried suppressed signal can be decoded to extract the original audio signal, the carrier must first be reinserted. This must be done accurately, otherwise the recovered audio signal will be unintelligible.
What describes a signal with a frequency of 20GHz in a satellite radio transmissions?
A downlink signal; a Ka Band signal
What describes a signal with a frequency of 20 GHz in satellite radio transmissions?
A downlink signal A Ka Band signal
How do you send a digital radio signal to a FM radio?
Frequency Modulation must have a carrier whereby the frequency can be modulated by the signal
What is the carrier voltage of modulated signal?
The 'carrier' is the signal that's flowing from the antenna into your receiverwhen there's no talk, no music, no sound of any kind on the signal. That'swhen you hear nothing out of the radio, because the radio is built to catchand work with only the changes of the carrier ... the modulation.
What does a radio wave transform radio waves into?
Sound.More informationAfter a modulated carrier signal has been received through the radio's aerial, the radio de-modulates it to release the live sound as picked-up from microphones in the radio studio (or was taken from recordings), which was then used to modulate the carrier signal at the transmitter.De-modulation that is done by a radio receiver can be described very simply as "removing the carrier signal to produce the sound".

What is a carrier and how does it affect what you hear on the radio?
A carrier is a high-frequency signal that carries information on a radio wave. The carrier frequency is modulated to encode audio signals, which are then transmitted and decoded by the radio receiver to produce sound. The carrier frequency determines the station you're tuning into on the radio.
What is the relation between carrier frequency and modulating signal?
If the modulating system is AM (Amplitude Modulation) then the amplitude of the carrier wave changes with the amplitude of the modulation. On a specrum analyser that shows up as frequency sidebands. If the frequency of the carrier waves depends on the amplitude of the modulating signal that is called FM (frequency modulation). On a spectrum analyser that shows up as sidebands also.
Which part of a radio receiver separates the audio signal from the carrier?
That's the "detector" or "demodulator" stage.
What is a modulation enveloped?
A: A radio transmission signal has an envelope where the carrier frequency are enveloped by the analog signal before demodulation. it can easily be seen by an oscilloscope
