Spectra of Underwater Light-Field Fluctuations in the Photic Zone
... The most evident feature of these spectra is the dominant peak that starts to develop at about 2 meters and becomes sharper with increasing depth. In studying some of our previous irradiance data we feel that this peak must become very sharp and move toward lower frequencies at increased depth. The ...

Broadly tunable, low timing jitter, high repetition rate optoelectronic
... and generation of low-noise millimeter wave signals [7]. In the most basic of these schemes, a continuous wave (CW) laser is sent though an electrooptic (EO) modulator driven by a stable radio-frequency (RF) source. The modulation creates side-bands around the CW laser frequency which are spaced by ...

A Custom built UHF to VHF downconverter
... It is suggested that a more affordable single channel FM demodulator be constructed as a cheaper alternative to this UHF downconveter that needs a 2m receiver. This UHF downconverter can be used as a basis and adding a 21.4MHz IF demodulator using the MC33xx or NJM33xx range of FM demodulator ICs an ...

... The advantage of this kind of reference signals is that the linear range of the modulation index can be extended by 15%. From Fig. 3 (a) and (b) it can be seen that having the same modulation index, the time tz1min is shorter in case of sinetriangular method than in case of SVM. This shows that the ...

Low-Power System for Detection of Symptomatic Patterns in Audio
... Abstract: In this paper, we present a low-power, efficacious, and scalable system for the detection of symptomatic patterns in biological audio signals. The digital audio recordings of various symptoms, such as cough, sneeze, and so on, are spectrally analyzed using a discrete wavelet transform. Sub ...
