Abstract :
AM/FM radio receivers with a digital tuning system are increasing in number, spreading from car radios to home stereos. A phase locked loop (PLL) frequency synthesized tuning system is the best answer for the reccent demands, that is, tuning accuracy, stability, easiness of operation and easiness of function expansion.
