Please, read Topic DCC Track Power 1 first.

This Squarewave AC at 10 kHz, or so, is used as the carrier of the information generated by the Control Station. Whatever the signal may be, it will be encoded onto the carrier wave, not unlike the method used in the realm of Radio and TV transmissions. There we refer to this process as the carrier being modulated. On your Radio you will find the terms AM and FM. AM stands for Amplitude Modulation, FM means Frequency Modulation.

Let us go back to the roller coaster. The higher and lower it travels, the greater the amplitude. The more often this occurs within a given distance, the greater the frequency.

Just exactly how modulation and digital encoding is accomplished I will not cover within this series of postings. This would require more detailed explanations and course materials not suitable for the purpose of this dissertation.

Now, this encoded signal, as described above, will find it's way, through the tracks, to a Decoder, such as the device installed in a given locomotive.

Hence, the Control Station is a Tansmitter, the Decoder serves as a Receiver. More stuff is going to happen.

To be continued.
