At a rate of 1M, the receiving sensitivity of the Bluetooth chip was tested, and during the test, it was found that the sensitivity may decrease whenever the frequency point of the test is 2416, 2432, 2448, 2464 and 2480. As can be seen from the figure, the sensitivity of adjacent channels is better than these channels, with 2480 channels being the worst sensitivity and a gap of 16M between channels. What is the reason and why this situation occurs, please help answer. Thank you!
