Fig.9 A.F. output as a function of r.f. input using the circuit of Fig.8 with that of Fig.1.
Fig.10 Suppression of cross-modulation as a function of input signal, measured in the circuit of Fig.8 with the input
circuit as shown in Fig.11. Curve is for Wanted Vo(af)/Unwanted Vo(af) = 20 dB; Vrfw, Vrfu are signals at the
aerial input, V'aew, V'aeu are signals at the unloaded output of the aerial.
Wanted signal (V'aew, Vrfw): fi = 1 MHz; fm = 400 Hz; m = 30%.
Unwanted signal (V'aeu, Vrfu): fi = 900 kHz; fm = 400 Hz; m = 30%.
Effective selectivity of input tuned circuit = 21 dB.
