| + | |||
| + | The code consists of two main parts, an autocorrelation algorithm that will be useful for detecting periodic signals, and a peak detector for detecting the peaks from the output of the autocorrelation function. | ||
| + | |||
| + | Distance between peaks = period of incoming signal. | ||
| + | |||
| + | The code calculates the frequency as: | ||
| + | |||
| + | freq_per = sample_freq/period; | ||

| + | ===== Concluzii ===== | ||
| + | |||
| + | This has been a pleasant and challenging experience that has taught me a lot about what can be done with creativity and a couple of wires (and the internet :D). | ||
| + | |||
| + | This has been a great opportunity for me to work with 2 things I like a lot (music and coding) and it has definitely inspired me to try out other projects like this is the future. | ||
