Q. Sampled-data and digital control systems?
These differ fromthe continuous-data systems in that the signals at one or more points of the system are in the form of either a pulse train or a digital code. Sampled-data systems usually refer to a more general class of systems whose signals are in the form of pulse data, whereas a digital control system refers to the use of a digital computer or controller in the system. The term discrete-data control system is used to describe both types of systems.
8 bit data to memory This form of the instruction is used to copy 8 bit data directly to the memory location pointed by register pair HL. The instruction format is
