Digital To Analog TV Decoder design And Fabrication

Abstract
Digital signal transmission with its high level of immunity to signal impairments has found a wide range of applications in telecommunication systems. Digital migration came forcefully with the global deadline set by the International Telecommunication Conference as of June 2015[1],[2], inspired by limitations of analog transmission systems and the high signal strengths of the digital transmission systems. This has been of much benefit to governments and consumers.However,the shift came with its challenges; high rate of unemployment,high cost of living and high inflation levels rendering digital migration expensive. This shift makes most people especially in developing countries stillstruggle in acquiring the costly digital compliant TV sets or buying set top boxes made for digital signal conversion.Moreover, maintenance of the digital transmission standards is also costly and thus untenable due to the monthly subscription cost. A simple non programmable digital to analog decoder based on frequency shift keying (FSK) digital modulation scheme and digital to analog conversion has been designed and implemented. It consists of FSK Modulation and demodulation using PLL implemented with CD4046, serial in parallel out (SIPO) shift register 74LS164 as a multiplexer, DAC 0808 converter, LC receiver and a DC power supply.
