What else can I help you with?
The amount of frequency deviation for a frequency-modulated signal is determined by the?
The signals frequency directly.
What is a powered audio mixer used for?
A powered audio mixer is used for combining, mixing, routing and changing the level, timbre or dynamics of audio signals. They can mix analog or digital signals depending on the mixer.
Application of signals and systems?
what is phase modulation changing of the phase depending upon the modulated signal is said to be a phase modulation
How is Sound produced in a audio devices?
Physical vibrations of speaker cones or metal plates by electromagnetic coils connected to the audio output AC signals from the audio amplifiers.
Can an analog tv receive a digital cable signal?
using two subcarriers and a main carrier signalaudio subcarrier is frequency modulated with audiocolor subcarrier is phase modulated with chromamain carrier is amplitude modulated with sum of video and modulated audio subcarrier & color subcarrier; then lower sideband is suppressed by a filter.closed captions are serial ASCII encoded characters embedded in vertical blanking of video signal
What does it mean when you say an infrared beam is modulated?
A small beam of light
How can infrared be used to communicate information?
Infrared can be used to communicate information by encoding data onto infrared light waves and transmitting them wirelessly between devices. The devices typically have infrared transmitters and receivers that can emit and detect the modulated infrared signals, allowing for data transfer such as remote control commands, data sharing, or proximity detection.
How can I block infrared signals effectively?
To block infrared signals effectively, you can use materials that are opaque to infrared light, such as metal or certain types of plastics. Creating a barrier with these materials can help prevent the transmission of infrared signals. Additionally, using specialized coatings or films designed to block infrared radiation can also be effective in blocking these signals.
What do you understand by modulation?
Modulation is a word applied to anything that varies in level. Brake pads are modulated in an anti lock braking system. The human voice can be modulated whilst singing to give a pleasing sound An audio signal can be superimposed upon a carrier wave in broadcasting. The carrier wave is amplitude modulated by the audio signal.
What characteristic two modulated signals are guaranteed to differ in wavelength division multiplexing?
color
The amount of frequency deviation for a frequency-modulated signal is determined by the?
The signals frequency directly.
What Technique is used 2 transmit audio signals of television?
what is the modulation used in telivision for audio signals
What are the AM receivers?
AM receivers are devices designed to capture amplitude-modulated (AM) radio signals. They work by detecting variations in the amplitude of the radio waves, which correspond to the audio signals being transmitted. Typically, AM receivers include components like antennas, demodulators, and amplifiers to process the received signal and convert it into audible sound. Common applications include traditional AM radios found in cars and home audio systems.
In wavelength division multiplexing two modulated signals are guaranteed to differ in what characteristic?
Color
What is fmcw radar?
frequency modulated continues radar for detecting the target it generates the signals by continuously.
Why is amplitude of demodulated FM signal much less than modulated signal?
because demodulated FM is an audio signal, which the frequency is much smaller that is why it can be transmitted alone. It need carrier which has large frequency. Modulated signal is an audio signal + carrier that is why the amplitude is higher.
What type of information is encoded in radio waves?
Radio waves can contain various types of information, such as audio signals for radios, television broadcasts, data transmissions for wireless communication devices, and radar signals for navigation and tracking purposes. The information is modulated onto the radio waves in the form of amplitude, frequency, or phase modulation.
