A receiver comprising, arranged in this order, an input section, an FM demodulator, to which a frequency-modulated input signal is applied, and an LF section, which FM demodulator comprises a pulse shaper and a low-pass filter the pulse shaper comprising a series arrangement of at least a ...
CONSTITUTION:When an FM input signal (ei) does not exist, and both differential signals e1', -e1' are larger than a threshold voltage (er), transistors TR3, TR6, and transistors TR4, TR5 become on and off, respectively, and a current flows to a transistor TR7. At the time of e1...
Utilize the all solid-state laser that provides more than 10,000 hours of uninterrupted service; a robust 80mm co-axial transmit/receive aperture; and a field replaceable fiber-coupled, photon-counting detector that needs no realignment.
On the return path, light that has been scattered off particles in the atmosphere enters the MiniMPLand follows the same path as the transmit beam. Once it enters the telescope,it is collected by the receiver and focused onto the detector (not shown). ...

From the set of 128 magnitudes from one FFT, the first moment (FM) is calculated by summing the result of multiplying each magnitude by the bin number of that magnitude. The envelope (iENVEL) is determined by comparing the integral of the total energy counting top down through the positive...

A receiver having, arranged in this order, an input section, an FM demodulator, to which a frequency-modulated input signal is applied, and an LF section, which FM demodulator includes a pulse shaper and a low-pass filter, the pulse shaper comprising a series arrangement of at least a ...
A pulse counting FM demodulator includes a differentiating circuit that differentiates an FM intermediate-frequency signal to produce a differentiated pulse signal. A trigger signal is generated based on the differentiated pulse signal and is used to control the charging and discharging of a capacitor ...
