What is the capture range of a phase lock loop?

Capture range: the range of frequencies over which the PLL can acquire lock with an input signal is called the capture range. This parameter is also expressed as percentage of fo. Pull-in time: the total time taken by the PLL to establish lock is called pull-in time.

What do you mean by lock range?

lock-in range: 1. The range of frequencies within which a closed-loop system can aquire and track a signal. (188) 2. The dynamic range within which a closed-loop system can aquire and track a signal.

What is capture mode and lock mode in PLL?

Once the input frequency is applied the VCO frequency starts to change and PLL is said to be in the capture mode. The VCO frequency continuous to change until it equals the input frequency and the PLL is in phase lock mode. If the two signals differ in frequency and/or phase, an error voltage ve is generated.

What is meant by lock range and capture range?

1. Lock range: The frequency range the PLL is able to follow input frequency variations once locked. 2. Mainly defined by the VCO range and limited by the phase detector. Capture range: The frequency range the PLL is able to lock-in when starting from an unlocked 3.

What does capture and lock range mean?

on the phase difference it gives the voltage which is passed through the low-pass filter and then. capture and phase lock lock. range is the range of frequencies over which the pedal maintain. lock to the incoming signal capturing means is a range of frequencies or which the barrel can acquire.

What are the applications of PLL?

Applications of Phase-Locked Loop

• FM demodulation networks for FM operations.
• It is used in motor speed controls and tracking filters.
• It is used in frequency shifting decodes for demodulation carrier frequencies.
• It is used in time to digital converters.
• It is used for Jitter reduction, skew suppression, clock recovery.

What is capture frequency?

In a radio receiver, the capture effect, or FM capture effect, is a phenomenon associated with FM reception in which only the stronger of two signals at, or near, the same frequency or channel will be demodulated.

Which is larger lock range or capture range?

Tracking range is the range of input frequencies over which the oscillator can stay in lock once lock was achieved. This is a wider range than the capture range since the comparator is already in lock, so incoming frequency variations are dealt with incrementally.
