1. a range of frequencies that can pass through a filter or electronic circuit with minimal attenuation
Usage: electronics; telecommunications

Examples

• The audio filter has a passband from 20 Hz to 20 kHz.
• Engineers designed the circuit to have a narrow passband for better selectivity.
• The radio receiver’s passband determines which frequencies it can detect.
• A wider passband allows more frequencies to pass through the system.
• The filter’s passband was adjusted to eliminate unwanted noise.
• Digital signal processing requires careful control of the passband characteristics.
