Resumo:

Programmable pulse generator (PPG) circuits using programmable interval timer chips are normally based on a PC or a microprocessor. We describe here a simple low cost programmable two-pulse generator using Intel 8253s in a stand-alone mode, eliminating the need for a PC or a microprocessor, though our design also can be operated via a PC or a microprocessor.
