HumBug Line Noise Eliminator

Features:

NO WAVEFORM DISTORTION - No Frequency Loss - No DC Voltage shift - No Signal Attenuation - No Phase Error

Although the HumBug uses a powerful signal processor, your signal is never digitized. Your signal will not suffer frequency loss, phase error, DC shift, or digitization. The HumBug continuously constructs a replica of evolving noise present on the input signal and subtracts this replica from the signal, leaving the physiological signal intact. It performs this function in the presence of biological activity even when noise characteristics evolve over time. The HumBug is not a filter, and does not create phase delays, amplitude errors, DC shifts or waveform distortion. Simply connect it between your preamplifier and any analysis equipment 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. The HumBug is effective at removing noise associated with inadequate grounding, ground loops, and electrical pick up. Common applications include noise elimination from signals using microelectrodes, skin electrodes (EKG, EMG, EEG), high gain amplifiers, magnetic sensors and audio equipment.
