Eliminates Electrical Interference
No Waveform Distortion
50/60 Hz Noise Eliminator
ELIMINATE 50/60 Hz NOISE AND HARMONICS WITHOUT FILTERING!
A New Solution
Quest is proud to introduce the Hum Bug -- a new approach to Noise Control. This is a powerful new technology for cancelling electrical interference in real-time, avoiding all of the traditional problems associated with notch filters. The Hum Bug constructs a replica of noise present on the input signal and continuously subtracts this replica from the signal as it passes through the instrument. It performs this function in the presence of biological activity even when noise characteristics evolve over time.
The Hum Bug is not a filter. It does not create phase delays, amplitude errors, DC shifts or waveform distortion. Simply connect it betweenyour preamplifier and any analysis equiment and it will automatically eliminate 50/60 Hz noise and harmonics with frequencies up to several kHz. Noise is eliminated without altering the signal of interest even when frequencies within the signal overlap with noise components. No settings or adjustments are required.
