The flexible pads are called base-isolators, whereas the structures protected by means of these devices are called base-isolated buildings. The main feature of the base isolation technology is that it introduces flexibility in the structure.
A demodulator is a circuit used in AM (amplitude modulation) and FM (frequency modulation) receivers to separate the information that was modulated onto the carrier from the carrier itself.It could be audio and/or video information, or other data. A demodulator is the analog of the modulator. A modulator modulates the carrier frequency, while a demodulator detects the modulation on the carrier wave and recovers the original lower frequency waveform at the destination.   For many years the modulated carrier wave was converted to a radio signal.
