App Description
This Prompts the user to enter values for bandwidths in MHz and dB to find S/N..
For a standard NTSC satellite signal enter baseband video bandwidth (BBV BW) in MHz, the the RF bandwidth (RF BW) of the signal transmitted over the satellite link in MHz, the receiving earth station C/N ratio in dB, the de-emphasis value P and the subjective improvement factor. Carson's rule is used to find the peak frequency and the baseband S/N ratio appears after the "Calculate" button is pushed.
As an example, input BBV BW, = 4.2, RF BW = 30, C/N = 15, P= 9 & Q= 8 and your output S/N should equal 50.54
