Figure 11.

An illustration of the interaction of wavelength (λ) and interelectrode distance (IED). The top left panel shows the muscle fiber action potential MFAP relative to G1 and G2 with an IED of 5 mm. The depolarization and repolarization peaks align with G1 and G2, respectively. The amplitude is normalized so that the maximum positive value is 1 unit. The grey sinusoid depicts the perfect addition wavelength (λ). The resulting bipolar MFAP has a peak amplitude of two units (bottom left panel). The top right panel shows the same MFAP but now the IED has been increased to 10 mm. The grey sinusoid depicts the wavelength (λ) associated with attenuation. Under these conditions, the bipolar MFAP experiences attenuation (bottom right panel). The peak amplitude of the bipolar MFAP was reduced to 1.438 units.
