Scalability of the IIR filter output in response to stimulation with different parameters in vitro. (a) Stimulation current and artifact during training and acquisition. (b) Recovered signal in 3 conditions: canceler OFF, canceler ON + filter retraining, canceler ON + coefficient scaling. The FFT window is highlighted with a shadow. (c) Frequency spectrum of the recovered signal. (d) Performance summary of the artifact cancellation scheme. The representative plots are from channel 0.
