Note 1. Input modulation’s product f 1 at 4.43MHz, 13.5MHz p–p deviation and f 2 at 6MHz p–p deviation, (PAL

chroma and sound subcarriers).

2. To output rms noise in 6MHz bandwidth with no input modulation, ratio of output video signal with input

modulation at 1MHz, 13.5MHz p–p deviation.

3. Output voltage is 600mV pk–pk and input test signal pre–emphasised video 13.5MHz p–p deviation.

4. See page 4

applies to application shown in Fig. 1 also refer to Fig. 4.
