Which symbol represents a crystal oscillator?

• A. Inductor symbol
• B. Crystal Oscillator symbol
• C. Transformer symbol
• D. Capacitor symbol

Answer: (B)

Understanding which schematic symbol corresponds to a crystal oscillator. A quartz crystal resonator is used as a precise frequency reference in oscillator circuits, so its symbol is distinct from common passive components. The crystal symbol is typically a small rectangle or crystal-like icon with two leads, sometimes labeled XTAL or QUARTZ. This makes it easy to recognize as the frequency-determining element, unlike the coil-shaped symbol for an inductor, the two parallel plates for a capacitor, or the paired-inductor arrangement for a transformer. So the symbol shown represents a quartz crystal resonator, i.e., the crystal oscillator.
