Abstract

PURPOSE:To obtain a miniature, lightweight and quick-response real-time imitation generator by reading out the antenna pattern of PROM by controlling an up- down counter according to a set angle. CONSTITUTION:Counter 11 counts up clocks and when comparator 12 detects a coincidence between the discrete value and a smaller digital set by digital switch 9 corresponding to a scan range, ternary counter 14 advances, so that circuit 17 will stay in a latch state until the content of counter 14 reaches three. Similarly, each coincidence output of comparator 13 making a comparison between the discrete value of counter 11 and a large digital angle set by digital switch 10 corresponding to the scan range and each coincidence output of comparator 15 changes the latch state of circuit 17 and counter 11 starts counting down. Therefore, addressing to PROM stored with one side of a symmetric antenna pattern is done by the count output of counter 11, thereby generating a real-time imitation antenna pattern by a miniature and lighweight constitution with quick response.
