carrier for high fidelity performance
5 Sensitivity at 45 dB signal-to-noise ratio (input
level of main sound carrier)

13 Weighted signal-to-noise ratio
14 AM suppression ratio
15 Selectivity
16 Spurious response due to r.f. non-linearity
17 Rejection of fundamental and harmonics of the sub-
carrier (systems with baseband sub-carriers)
18 Rejection of unwanted signals from the video channel
19 Variation of the rejection of unwanted signals from
the video channel with time
