NOTES TO THE CHARACTERISTICS

1) INTERMODULATION SUPPRESSION

α2 =

(signal)(at1KHz)

(spurious)(at1KHZ)

α3 =

(spurious)(at1KHZ)

measured with : 91% mono signal; 9% pilot signal; fm=10KHz or 13KHz

2) TRAFFIC RADIO (V.F.) suppression

α57 (V.W.F.)=

(spurious)(at1KHZ ±23Hz)

measured with : 91% stereo signal; 9% pilot signal; fm=1KHz; 5% subcarrier

(f=57KHz, fm = 23Hz AM, m = 60%)
