The Deveplopment of Monolithic Microcomputer in Frequency-Hopped Frequency Synthesiser

In this paper a new type of frequency-hopped frequency synthesiser is presented. The frequency synthesiser is consisted of a phass-locked loops in which a integrated circuit MC145146 be used. A monolithic microcomputer is employed to control the frequency divided ratio of the PLL. The monolithic microcomputer control the frequency synthesiser worked in FH form by a frequency seeking chart.
