Vertical cross phase demodulation circuit |
| abstract |
In the vertical cross phase demodulation circuit, a simple circuit is used to eliminate DC offset. When a clock reproduction circuit 6 is locked, a phase comparator 9 detects a level difference ΔE between a zero crossing point and a true 0 level. The level difference ΔE represents an offset level and maintains the level difference ΔE of the original level output. After being flattened by the LPF 12, the level difference ΔE is input to adders 14 and 15 so as to eliminate a DC offset. |
