Передавач цифрового телебачення стандарту DVB-T2

Abstract

In this master's qualification work the digital broadcaster DVB-T2 with high-speed performance has been developed. The DVB-T2 standard analysis, the study of the circuits of the digital television transmitter and the choice of the circuit with direct quadrature modulation were completed. The modern element base, on which the electric principles scheme was developed, was chosen. Also in the work carried out electrical calculation of the cascade of amplification and LPF; Computer simulation of DAC and LPF was carried out, calculation of the printed circuit board of the device was carried out.
