Diagram Eye Imaging
Chýlek, Richard ; Kratochvíl, Tomáš (referee) ; Říčný, Václav (advisor)
The aim of this bachelor´s thesis was to design an adaptor for imaging the eye diagram of digital video signals in the basic zone. Adaptor is a device by which we can illustrate the signal distortion resulting from the passage through the transmission channel, using the XY displeying.This adaptor should be designed with the symbol timing recovery. This means that the adaptor has been divided into two parts. Part of the broadcast, which consists of a units generator timing signal, generator block and pseudorandom sequences. These blocks of me created a 127-bit sequence with different frequencies (2 MHz, 4 MHz, 8 MHz and 16 MHz). In the evaluation of the adaptor, which is composed of symbol timing recovery, frequency dividers, low pass filter and all-pass network for phase synchronization and adjustment signal amplifiers, the signal is divided into two branches. The first walked through a matching amplifier and led to vertical clamps oscilloscope. The second passes through progressively above districts and ultimately led to the horizontal clamp oscilloscope. The individual blocks were designed in detail and implementation schemes were drawn up for both of the adapter. From these themes, I then proposed a DPS for each of the adaptor. They were blocks of broadcast adaptor, evaluation of the adaptor, the blocks of resources and subpanel for two main blocks. The result of this work is complete documentation for the implementation of this adaptor. Direct implementation is not required.
