Measuring frequencies
=====================

Method 1:
+ quite accurate for higher frequencies, as long as sufficiently large window sizes are used
- overshoots and undershoots for lower frequencies as window sizes cannot be chosen infinitely large
- latencies for updates due to large window sizes

=> window size is always a compromise between accuracy for low frequencies and update latencies, for our purposes a window size of 100 ms, i.e. 100 clocks, was feasible


Method 2:
+ immediate update
+ good for lower frequencies
- low accuracy for higher frequencies
