Modem is a device which modulates and demodulates a signal.
to send power through them so that electricity can get to your home
Pores enable the nucleus to send and receive information through the nuclear membrane.
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
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.
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.
Doesn't really matter what kind of energy source you use, water isn't an efficient media to transmit electricity through.
Binary telephone signals.
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.
The dendrites of one neuron send electrical impulses called synapses to the axons of other neurons to transport information.
no, not by itself. Although, it does use electricity which is used to send a current through the copper ring creating a magnetic field.
