You can generate: - Single type signal (sinusoidal, square, noise, etc) - Sweep (chirp) signal (linear or exponential) - Click: ON-OFF sine wave with any duty cycle and ON frequency - Merged sound of any number of tones or sweeps 更多 新...
Based on the theory of Omura et al. (2008), we predict the sweep rates of chorus elements observed by the THEMIS satellites. The predictions use independent observations of the electron distribution functions and have no free parameters. The predicted chirp rates are a function of wave amplitude...

I'm trying to write a simple tone generator (below) that picks a random frequency between 13kHz and 16kHz and plays a pure tone at a set dB volume. But for some reason, the amplitude/volume of the tone increases with frequency, so higher frequency tones all have highe...
As previously mentioned, in my implementation the AVR is in power-down mode during all idle times, essential when building my version of the hardware. You can get my codehere on github. Alternatively the code on Arnie’s repository will work – provided that internal pull-ups are enabled on...
Their software has the "more" section, and in there, for each channel, I can select "Squelch Mode" to be "CTCSS/DCS" Once that is done for each channel and programmed, the tone squelch works. It seems that Chirp is not setting this value when TSQ is selected. Thanks, Larry...

(ODSB)–RoF system and is tolerable for power degradation due to a chromatic fiber-dispersion, through a standard single-mode fiber (SSMF) carried by a continuous wave (CW) laser at 1550nm of laser-spectral width varying from 100MHz to 100kHz with CW power of 10mW that modulates a ...
