well;a repeater IS an amplifier...amplifying the input signal out to the other side. However, repeaters also amplify noise as well therefore limiting the number of repeaters used in any given network segment. Intelligent repeaters and bridges will amplify signal, but without the noise...the signal being regenerated before sending....a repeater IS an amplifier...amplifying the input signal out

while and a good FM radio will save you cash in the long run. The reason why FM is so much better is the way it sends the signal to the car. I dont know if you understand how AM and FM work, but here goes my explination the reason why the signal is "clear":All RC radios send out sine waves at 75MHz or 27MHz 75 million waves per second or 27 million waves per second This is you carrier signal

well,The world of science and engineering is filled with signals: images from remote space probes, voltages generated by the heart and brain, radar and sonar echoes, seismic vibrations, and countless other applications. Digital Signal Processing is the science of using computers to understand these types of data. This includes a wide variety of goals: filtering, speech recognition, image enhancement

of an electrical signal. In most applications the graph shows how signals change over time: the vertical Y axis represents voltage and the horizontal X axis represents time....well, The oldest form of oscilloscope with all popular operating platforms Zoom-in and zoom-out Multi-color displaysThe oscilloscope is basically a graph-displaying device - it draws a graph of an electrical signal. In most applications

or digital input signals and outputs that into a single line.An electronic multiplexer makes it possible for several signals to share one expensive device or other resource, for example one A/D converter or one communication line, instead of having one device per input signal.In electronics, a demultiplexer or demux is a device taking a single input signal and selecting one of many data-output-lines, which

A reproducing circuit is disclosed having a photo-diode for extracting a signal component of a monitor signal from an electric signal converted from an optical signal using a band pass filter 108 and an envelope detector circuit 111. The output of the photo-diode 106 is smoothed by a capacitor 12 via a buffer amplifier 11. A threshold voltage control circuit 13 converts the smoothed signal voltage with a

://www.blurtit.com/q811922.html...Time-division multiplexing TDM is a method of putting multiple data streams in a single signal by separating the signal into many segments, each having a very short duration. Each individual data stream is reassembled at the receiving end based on the timing.The circuit that combines signals at the source transmitting end of a communications link is known as a multiplexer. It accepts

values between the circuit elements....well blogger01 mixed circuits are A mixed-signal integrated circuit combines analog circuits with digital signal processing DSP circuits on a single semiconductor die. An integrated circuit that includes both analog and digital circuitry but no DSP, like a 555 timer, is generally not considered a mixed-signal integrated circuit.Typically, mixed-signal chips perform some whole

well Rakesh, Modem is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data. Modems can be used over any means of transmitting analog signals, from driven diodes to radio.The most

hi roshank!Spread-spectrum techniques are methods by which energy generated in a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth://en.wikipedia.org/wiki/Spread spectrum...well;Spread spectrum is a form of wireless communications in which the frequency of the transmitted signal is deliberately varied. This results in a much greater bandwidth than the signal would

hi sahil You can boost the signal range of a WiFi computer network in several ways:Answer: reposition your router or access point to avoid obstructions and radio interference. Both reduce the range point to the second one with Ethernet cable; home wireless routers and/or APs dont normally communicate with each other directly.add a bi-directional WiFi signal amplifier to wireless devices as needed.

controlled by adjusting the speed of pump.DC motor drives act as an interface between a controller and the motor. The drive must match the control signals voltage and power levels and signal type analog or digital. The drive produces power conversion, amplification, and sequencing of waveform signals. Types of DC motor drives include adjustable or variable speed control, servo control, and integral motion
