What is the capture frequency range

Assignment Help Electrical Engineering
Reference no: EM13687085

A theory explanation is needed of the mention below.

Background: Theory on FM modulation, PLL and VCO and how you determine R1, R2, and C1 values from the data sheet of 74HC4046.

What is the capture frequency range and what is the lock frequency range in PLLs?

Phase-locked loops (PLLs), especially in monolithic form, have significantly increased use in signal-processing and digital systems. Frequency modulation (FM) demodulation, frequency shift keying (FSK) demodulation, tone decoding, frequency multiplication, signal conditioning, clock synchronization, and frequency synthesis are some of the many applications of a PLL. Th PLL described in this application report is the CD4046B, which consumes only 600 µW of powe at 10 kHz, a reduction in power consumption of 160 times when compared to the 100 mW required by similar monolithic bipolar PLLs. This power reduction has particular significance for portable battery-operated equipment. This application report discusses the basic fundamentals of PLLs, and presents a detailed technical description of the CD4046B, as well as some of  its applications.
