Chapter 5: Components, Part 2 Detectors and other Circuits
Open-loop sweep, closed-loop sweep, and discriminator-aided acquisitions are the methods that are covered. The phase/frequency detector uses discriminator-aided acquisition and is the most popular choice. Clock-recovery circuits cannot use phase/frequency detectors. Consequently, these circuits require an acquisition aid.

Advanced Metal Detector
Dev presents two versions of metal detector circuitry. First, he updates the traditional beat frequency oscillator approach, to use a digital mixer. Second, he builds one more suitable for a child, using a PIC16 microcontroller that allows push-button zeroing and adjustable sensitivity.
operational amplifier
Its really this period of the decay that the circuit is trying to amplify & detect, because this decay signature changes when the metal detector is above a piece of foreign metal as the figure posted by "Voltage Spike" suggests. The voltage at the non-inverting input (call it Vx) to IC4 is a virtual ground, held at Vx = 9V.
