rmeister "Sure, but anything above 7kHz will need disabling echoCancellation. gh-pages is currently set up with 2450 and 4900 Hz, echoCancellation active. F..." | Read more » over 4 years ago

rmeister "If the nanite's output is 3V, then the voltage at your phone will be about 3V as well for the first few periods. But after a couple of periods the ..." | Read more » over 4 years ago
rmeister " For an (unequally) attenuated signal, the amplitudes for f_low and f_high are uneven. In this case, the amplitude for f_high is very low. Cool, ..." | Read more » over 4 years ago
rmeister "Oh yes, the signal is still attenuated. Didn't see that on my phone yesterday. " | Read more » over 4 years ago
rmeister "Cool, looks good. Thanks for your effort! Maybe try switching the wires to sleeve and ring2. " | Read more » over 4 years ago
rmeister "Probably you ment an other circuit, as I see you have a background in electronics engineering :D " | Read more » over 4 years ago
rmeister "It's a voltage divider (so your phone won't be damaged by a too large voltage) and a high-pass filter (removes DC voltage). Would you give it a tr..." | Read more » over 4 years ago
rmeister "Wow, thanks @kinasmith! Probably this pulses are sort of a presence detection for the microphone? Could be an issue, but most of the signals from ..." | Read more » over 4 years ago
