PREFERRED TERM
Frequency analyser
DEFINITION
Device that processes the signal from the analog-to-digital converter and calculates the Doppler spectra. English
Sistema che converte il segnale digitale in uscita dal convertitore analogico-digitale in spettri Doppler. Italian
Dispositivo que procesa la señal proveniente del convertidor analógico-digital y computa el espectro de frecuencias. Spanish
处理来自模拟数字转换器的信号并生成多普勒光谱的设备。 cn

EDITORIAL NOTE
- Once the analog signal is converted to a digital signal, a frequency analyser is used to determine its frequency spectra. This device yields the frequency spectrum of the dowmixed signal (original signal from the laser source + backscattered signal), therefore the Doppler frequency shift.
