• Manufacturer Part Number: la1867nm
• Description: Car Radio Single-chip Tuner System
• Manufacturer: Sanyo Semiconductor Corporation

• In the technique in which the S-meter AC component is detected directly the noise amplifier gain is determined by
• In the technique of Figure 4, in which multipath is detected using the S-meter high area components, and In the
R
provided with capacitor C
technique of Figure 3, in which the NC HPF noise is detected, the noise amplifier gain is determined by R
internal 30 kΩ resistance as shown in Figure 6. The frequency characteristics of the circuit are determined by the
capacitor C
