(4) SNC and HCC connection circuits when coupled with the IF stage.
Fig. 1 shows sample S/N characteristics via antenna inputs when SNC and HCC are connected with the IF stage by an
external circuit.
(5) S/N improvements in region C of Fig.1
Because S/N ratios deteriorate even further in the region C of Fig. 1, it is better to improve the S/N in this region with
IF mutings. The LA1140 is available to linearly vary the IF muting. Employment of the LA3370 together with the
LA1140 further enhances S/N improvement.
(6) Using the HCC terminal for muting
Muting in the neighborhood of 37dB are feasible by utilizing HCC functions as muting functions when used in home
stereos and no need exists to suppress treble noises. Fade-in and fade-out of mutings, permitting delightful, shock-noise-
free muting are possible by providing a time constant to the pin 7 control.
(7) VCO damping
VCO oscillations can be damped by applying a voltage not less than 7V to the HCC terminal (pin 7) to enter a monaural
mode. At this time, both SNC and HCC are in an off mode. Fig. 9 shows flow-in current by voltages applied to pin 7.
(8) Separation control terminal
Separation is controlled by controlling the main signal level.
The controllable separation (ratio of sub signal to main signal) range of the input composite signal is approximately as
follows :
Sub signal level
m =
Main signal level
(at peak level)
0.7 < m < 1.25
