Visual grub new name1/28/2024 ![]() ![]() Not really a question-Just a piece of hardware infoĮarlier this week, I started having problems with the local electricity supplier. This is what I have come up with so far - although I believe it's far from ideal. The goal of this element of the projects is to be able to use the first 5 harmonics and a sampled period of the guitar signal for further DSP. *Anti-aliasing for the ADC *Guitar signal of 500mV Vp-p max *ADC input range 0-3.3V *5V single supply *Frequency range from 82Hz and 5875 Hzĭoes anyone have any suggestions of a circuit that I can use? I have TL082, LM358 and LM741 opamps available, but I am open to other suggestions. So far, I have not come across any solutions that I am happy with. I am using an STM32F407 Discovery board( ). This means that I need to be sampling at about 58.75 kHz, which is possible with the microcontroller and it's DSP functions. I am trying to prepare my guitar signal for as best as possible ADC response in order to detect harmonics to the 5th of the highest note of the guitar (1175 Hz for 22 frets), which is about 5875 Hz.
