Hello Community!
During My project of "removing motion artifacts from the PPG signal" I faced many problems related to the pulse sensor that it didn't give me any good signal, and it is for commercial use, that's why I decided to build the sensor and replace it with an electronic circuit using...
Hi,
I want to sample 4 audio sources which frequencies would be between 30 kHz and 40kHz (ultrasonic signals). Is there a microcontroller with ADC that could do that?
Hi everybody! I need to recover the signal captured by 3 or 4 hydrophones and doing the respective signal processing (amplification, filtering, ADC). What kind of microcontroller should I use in order to do that? The recovered signal should be between 25 kHz and 200 kHz.
Thanks!
