In methods in which the S-meter AC
components are detected directly, the noise
amplifier gain is determined by R2 and the
30 kΩ internal resistance, as shown in
Figure 1. A certain degree of filtering
characteristics can be provided with
capacitor C1.
In methods in which the S-meter high area
components are detected, or the NC HDF
noise output is detected, the noise amplifier
gain is determined by R2 and 30 kΩ as
shown in Ffigure 2. Here, the frequency
characteristics are determined by C1.
During discharge, the MRC detector time
constant is determined by RS (1 kΩ) and
CA. During charge, it is determined by IC
and CA.
Attack time = CA × RS
(Stereo → mono)
Recovery time = CA × RA
(Mono → stereo)
Unit (resistance:Ω, capacitance:F)
