An electronic device and a method for implementation for signal denoising based on adaptable deep neural networks. The electronic device receives training data comprising a first bio-signal and a second bio-signal that is different from the first bio-signal. The electronic device computes a weighted sum of the first bio-signal and the second bio-signal. The electronic device generates a mixed signal based on the weighted sum. The electronic device generates an output signal based on application of a denoising neural network (DNN) on the mixed signal. Further, the electronic device computes a loss based on a comparison of the output signal with the first bio-signal and trains the DNN for a number of epochs until the computed loss is below a threshold.

An apparatus for measuring magnetic fields from a subject's organ comprises a plurality of unshielded magnetometers in a three-dimensional arrangement. A respective pair of magnetometers, in the plurality of magnetometers, has a respective known separation. Each magnetometer in the plurality of magnetometers is configured to simultaneously detect a biomagnetic field from at least a portion of the subject's organ and a background magnetic field and output a signal indicative of the detected biomagnetic field and the background magnetic field.

According to the present invention, a filtering apparatus includes an FIR filter that has multipliers arranged to multiply input digital data having their respective different input time points by respective variable tap coefficients. The variable tap coefficients are each switched from a first tap coefficient to a second tap coefficient sequentially for the input digital data from later to earlier input time points. The first tap coefficient is arranged to cause the FIR filter to serve as a low-pass filter with the cut-off frequency set at a first frequency. The second tap coefficient is arranged to cause the FIR filter to serve as a low-pass filter with the cut-off frequency set at a second frequency different from the first frequency.
