1. of or relating to an electronic filter that allows low frequencies to pass while blocking high frequencies
Usage: technical; electronics

1. an electronic filter that permits the passage of low-frequency signals and attenuates high-frequency signals
Usage: technical; electronics

Examples

• The audio engineer applied a lowpass filter to reduce high-frequency noise.
• A lowpass circuit is commonly used in speaker systems to isolate bass frequencies.
• The lowpass design has a cutoff frequency of 1 kHz.
• Digital signal processing often employs lowpass filtering to smooth data.
• The lowpass response of the amplifier prevents distortion from ultrasonic signals.
