For example, in a modem, which is a contraction of the terms modulator /demodulator, a demodulator is used to extract a serial digital data stream from a carrier signal which is used to carry it through a telephone line, coaxial cable, or optical fiber. Contents.here are several ways of demodulation depending on how parameters of the base-band signal such as amplitude, frequency or phase are transmitted in the carrier signal. For example, for a signal modulated with a linear modulation like AM (amplitude modulation), we can use a synchronous detector.
Newer pressure filtration systems capable of nanofiltration and reverse osmosis filtration will remove salts, and reduce hardness. A descaler does not remove dissolved solids; it attempts to prevent the solids from being deposited inside pipes, on fixtures, etc.The word conditioner is very vague and is commonly used in reference to lime scale prevention.ewer pressure filtration systems capable of nanofiltration and reverse osmosis filtration will remove salts, and reduce hardness.
