Hello Dora,
Thanks for your fast reply. I think about something like this:
a device that measures the loudness of sound for different frequencies. This device is divided in three
parts: a microphone that captures the sound, one A/D converter that samples
the sound and one FPGA which analyse the data using an FFT algorithm.
LEDs connected to the FPGA are used to indicate different output levels. A
db(A) filter is applied that weights each frequency, before the different output
levels are measured for each frequency.
Or something like this, maybe for captuaring vibration (for example from electrogenerator ect.).
I dont know from what to start, and have not so good imagine how it all works. Sorry for previous messages, maybe not so understanding.
Maybe someone can help me in that. Thanks.
Best regards,
Karper.
