Hi! I would like to construct a digital circuit as like how computer transmit data. My problem is how can I make start bit and stop bit for my 7 bits data?and how can the receiver knows that that is start bit and not the data?(I confuse at this part) While sending data, how can I scrambling the data?And actually does this scrambling process important in sending data? To make the sending data clear, I want to increase the clock pulse between the data during sending.How can I do it? Thanks!
