This exhibit in the shape of a pen is includes a large-screen indicator, which faces the video camera. The video-output terminal of the camera is connected to the video-input terminal of the indicator. The indicator constantly transmits its own images to the camera lens. Each time the indicator transmits an image, the image becomes smaller. The input and output signals are repeatedly iterated producing a series of similar, small graphs.

This thesis proposes a novel method of retiming E1 signal of the SDH output and using it as a reference synchronization signal for Trunking Gateway. The proposed retiming method can generate the E1 signal of TG input in comply with the maximum relative time interval error requirement of 52.5ns specified in the PRC-Generation standard. The method successfully reduces the E1 signal error level to a smaller margin of 300ns than that of the PRC-output standard.
