🔍 Key Concepts

• Role of a phase comparator in detecting phase difference between signals • Purpose of a loop filter in a PLL system • Function of a voltage controlled oscillator (VCO) and frequency dividers in generating stable, selectable output frequencies

💭 Think About

• Which building blocks are absolutely essential for comparing the reference frequency to the output frequency and then correcting any error? • Think about how a PLL generates many different output frequencies from a single reference: what components are needed to divide or adjust frequencies under control of a feedback loop? • Which option contains blocks that clearly form a closed feedback loop from reference input, through comparison and correction, back to the oscillator?

✅ Before You Answer

• Make sure the option you pick includes a phase comparator (or equivalent) and a loop filter, as these are core PLL elements. • Verify that there is a controllable oscillator (like a VCO) and some form of frequency division or ratio setting, which allows synthesis of multiple output frequencies from one reference. • Eliminate any options that include blocks mainly used in detection or simple mixing but do not clearly support a feedback control loop.
