PRELIMINARY DATA SHEET

MSP 3400C

3. Application Fields of the MSP 3400C

The MSP 3400C processes TV sound according to the

German and Korean two carrier system and the com-

monly used satellite systems. In the following sections,

a brief overview on the German FM-Stereo system

shows what is required of a multistandard audio IC.

3.1. German 2-Carrier System (DUAL FM System)

Since September 1981, stereo and dual sound pro-

grams have been transmitted in Germany using the

2-carrier system. Sound transmission consists of the al-

ready existing first sound carrier and a second sound

carrier additionally containing an identification signal.

More details of this standard are given in Table 3–1.
