What is an amplifies?
A device used to make an instrament louder, usually an electric guitar. Sound signals have a certain amplitude behind them (power). If the signal is week, it is difficult to hear and transmit. Therefore, you need an amplifier to add power to a signal in order for it to be heard and transmitted.
Is a moderm converts the digital signals from a computer into signals that can travel over a network?
Yes, a modem (modulator-demodulator) converts digital signals from a computer into analog signals that can be transmitted over various types of networks, such as telephone lines or cable systems. It also performs the reverse function, converting incoming analog signals back into digital form for the computer. This process enables communication between digital devices and external networks.
What does a preamplifier do?
A pre-amp is a type of amplifier used in sound systems. It usually amplifies the signals coming from microphones or low amplitude signals coming from any other sources. The pre-amplified signals can then be amplified to a greater extent when the signals are sent to the main amplifier. Because some microphones are low voltage or are wireless the signals are weak compared to older style microphones.
Can you use a receiver as an amplifier?
Yes, a receiver can function as an amplifier, as it typically includes built-in amplification for audio signals. In this context, the receiver amplifies the audio from various sources, such as radio, streaming, or physical media, before sending the output to speakers. However, while all receivers have amplification capabilities, the quality and power of that amplification can vary widely between different models.
What device modulates outgoing signals and demodulates incoming signals?
To receive a Satellite signal, you need a LNB which is attached to your satellite dish--The LNB and dish is determined by which satellite TV service you have--either Dish Network or DirecTV. The satellite dish is pointed in a particular direction to pick up the correct satellite orbiting the sky. You will also need a satellite receiver, which is "wired" to the LNB and also is attached to your television.
What is a bilinear amplifier?
it amplifies both the incomeing and outgoing signals on CB radios
How does a cordless phone receive its signals?
Cordless phone amplifies signals to and from phone-line interface, user controls and speaker phone. It broadcasts and receives radio signals to and from the handset.
What are the difference between Erbrium doped fiber amplifier and semi-conductor amplifier?
A doped fiber amplifier amplifies light in the fiber as a LASER.A semiconductor amplifier is an electronic circuit that amplifies electrical signals.
Which network device regenerates the data signal without segmenting the network?
The network device that regenerates data signals without segmenting the network is a repeater. Repeaters are used to prevent attenuation of signals.
What term means to issue signals along a network medium such as a cable?
which term means to issue signals along a network medium such as a cable
What did Lee DeForest invent?
De Forest invented the Audion tube, a vacuum tube that takes relatively weak electrical signals and amplifies them.
What signals are used for the maintenance and overall operation of the network?
Network Management signal
What amplifies low frequency signals?
An amplifier! Amplifiers are designed for particular band-widths from fractional-Hz, and even d.c., upwards, but that band can be very wide.
What amplifies sound waves by as much as 20 times their original intensity?
A microphone and an amplifier with a loudspeaker does this. The microphone converts the soundpressure to electric signals. The amplifier amplifies these signals and the loudspeaker converts back the electric signals to sound pressure. Our ear drums are moved by the sound pressure as a sound field quantity. It is not the sound intensity as an energy quantity.
