Hi, I'm just going to quote the whole word problem b/c I don't fully understand it. (Figure 2 is a parallel-in, serial-out shift register w/ a series of and/or/inverter gates that are used to establish preset and clear conditions when the "load" signal is activated)
"A circuit like the one in Fig. 2 is used in modems to convert an 8 bit byte into a serial stream of information. In order for the circuit in Fig. 2 to operate, it must continually get loaded with a byte and serially transmit that byte out. Several additional circuits are required, including
1) a circuit to load the next byte into the parallel to serial converter after the last byte had been transmitted out.
2) a circuit that will stop transmission if a problem occurs.
3) a circuit to generate a clock signal.
Propose a block diagram that will provide these functions."
For the first part, I was thinking about using a JK FF but I have no idea how to make it send out the last byte before the next one is loaded in.
For part 2, I have no idea how to make it stop when a problem occurs, any tips or devices I should use?
For 3 I was just going to add a neg. edge triggered FF, but don't really understand what is needed to generate a clock signal, one was just presented to us usually.
I am somewhat lost here and could really use any help.
Thank you!
