At the middle hole between top of z and bottom of z, it is expected that odd integers of z will drop out and measure to be zero. What is observed is cancellation of odd integer values of z. This data shows a few more frequencies we didnt see before at 2319 Hz and 2302 Hz. Also its observed that at higher frequencies the more noise observed. Also another random frequency is observed like from before but at 2785, 20 Hz higher than predicted.
