An envelope detector (square-law-type detection) on the user terminal is used to down-convert the mm-wave signals and eliminate the frequency instability and poor phase-noise characteristics of the two independent signals.
After passing through the antennas, at the designated user terminal nn the received downlink and P2P signals are down-converted to their associated IFs by the envelope detector.
ASK receiver front ends typically comprise three blocks an input band pass filter to discern the carrier frequency from a broadband input noise spectrum, am envelope detector to extract the information of interest and a comparator to obtain binary outputs for PC software analyzer.
To date, network pages have been constructed for three of Stable Micro Systems' key instruments; the Dough Inflation System, Acoustic Envelope Detector and Dough & Gluten Extensibility Rig.
The output voltage of the envelope detector is proportional to the magnitude of the instantaneous RF input voltage.
s Stable Micro Systems, a provider of texture analysis equipment, has designed and launched its new Acoustic Envelope Detector.
The signal is then passed through an envelope detector (demodulator), which yields a square wave output.
ADI's ADL5511 TruPwr[TM] rms and envelope detector is highly accurate and simplifies envelope extraction of high peak-to-average modulated signals in wireless, instrumentation, military and broadband applications.

It is then transformed into a DC signal by an envelope detector.
An envelope detector essentially provides an output that is the modulation envelope of an IF signal.
Separate signal envelope and noise envelope detectors in the transmit and receive channels allow transmit/receive changeovers to be accurately based on the difference between the transmit and receive input signal levels.
