Another type of demodulator, the product detector, can provide better-quality demodulation with additional circuit complexity. V. An example is the X demodulator used in the X/Z demodulation system. The sensor performs its own modulation, demodulation, amplification, and output switching. Another application of the analytic representation of a signal relates to demodulation of modulated signals. The FM modulation and demodulation process is identical in stereo and monaural processes. Range demodulation is limited to 1/4 wavelength of the transmit modulation. The first use for the diode was the demodulation of amplitude modulated (AM) radio broadcasts. They are connected to an oscillator and subsequent frequency demodulation electronics to obtain digital waveforms. Both ASK modulation and demodulation processes are relatively inexpensive. That limit depends upon the type of modulation and demodulation. Newer systems convert the alternating signal directly before performing digital demodulation. QAM demodulation requires a coherent receiver. These properties are used for computer clock synchronization, demodulation, and frequency synthesis. They perform analog functions such as amplification, active filtering, demodulation, and mixing. As with all radio, this is done by the modulating and demodulation of carrier waves.
