Electrical signals are either direct current (DC) or alternating current (AC).
For DC signals, information is carried by the existence of a DC level, or it's absence. This is binary signalling, and communicates either a '1' or a '0'.
An AC signal conveys information by either changing one of the three properties that AC signals have:
1) changing the amplitude of the signal (this is amplitude modulation, like an AM radio)
2) changing the frequency (this is frequency modulation, like an FM radio station)
3) changing the phase of the AC signal. This is used in the faster of the old-style computer modems, as well as DSL modems

What is the difference between a conductor and an insulator in terms of electrons?
Electrons are part of an atom, in elements etc. Electrodes are types of medical equipment places on certain parts of your body, that send electrical pulses to your muscles to stimulate them.
What is Discrete time signal processing?
While processing a signal through a channel, it is preferred to sample it. It is because of the following reasonsAs we send only the samples, the gap between samples can be used to send another signal.Multiplexing is possibleSamples occupy less space than signalsTotal signal may not be required to recover dataAnd hence we use samples which are nothing but discrete time signals. hence, it is called discrete time signal processing.
What is Vulnerable time in terms of CSMACD?
CSMA\CD means that when a Clint want to send a signal if is it free it will send the signal and it happens in other Clint at the same time so the signal will crash and then they will try again later after period of time.
What kind of signal does the lambda sensor send?
oxygen sensor
How can you transmit voice signal using ask modulation?
The only way is to digitize the audio signal and send it as data
Which of these is not a type of signal used to send information through electricity?
transistor
What types of signal used to send information through electricity?
Information can be transmitted through electricity using various types of signals, primarily analog and digital signals. Analog signals represent information as continuous waveforms, varying in amplitude or frequency, while digital signals encode data as discrete binary values (0s and 1s). Other forms include pulse-width modulation (PWM) and frequency modulation, which are used in specific applications for efficient data transmission. Each signal type has its advantages depending on the context and requirements of the communication system.
Who invented ways to send electricity through wires?
my girlfriend
How does radiation send and receive signal?
Radiation sends and receives signals through electromagnetic waves, which propagate through space. When a transmitter generates an electromagnetic wave, it modulates the wave's amplitude, frequency, or phase to encode information. This signal travels through the environment and can be detected by a receiver, which demodulates the wave to extract the original information. The effectiveness of this communication depends on factors like frequency, distance, and obstacles in the signal path.
What is definition of the word modem?
Modem is a device which modulates and demodulates a signal.
How do power lines be used?
to send power through them so that electricity can get to your home
Which feature enables the nucleus to send and receive information through the nuclear membrain?
Pores enable the nucleus to send and receive information through the nuclear membrane.
Distinguish between a signal element and a data element?
Signal Element Versus Data Element: Let us distinguish between a data element and a signal element. In data communications, our goal is to send data elements. A data element is the smallest entity that can represent a piece of information: This is the bit. In digital data communications, a signal element carries data elements. A signal element is the shortest unit (time wise) of a digital signal. In other words, data elements are what we need to send; signal elements are what we can send. Data elements are being carried; signal elements are the carriers.
What is an high definition radio receiver?
It is a technology used by both AM and also FM radio stations to send information and audio through a digital signal. For a more in depth information refer to www.hdradio.com/what-is-hd-radio or http://en.wikipedia.org/wiki/HD_Radio.
What kind of battery will you need to send electricity through water?
Doesn't really matter what kind of energy source you use, water isn't an efficient media to transmit electricity through.
What type of device converts an electrical signal into electromagnetic waves for transmission through a channel?
A transmitter is the type of device that converts an electrical signal into electromagnetic waves for transmission through a channel. Transmitters are commonly used in communication systems such as radios, TVs, and mobile phones to send information wirelessly over long distances.
How do nerve cell works?
The dendrites of one neuron send electrical impulses called synapses to the axons of other neurons to transport information.
