Clamp current fluctuations in frog skin of areas down to 0.07 cm2 are dominated by low frequency components (less than 100 Hz). Patch clamp of 0.001 cm2 under high density fluorosilicone oil exhibits components up to 5000 Hz, often including a peak in the current power density spectrum. The admittance spectrum also exhibits a peak at the same frequency. In some skins no peak was observed, but the break in the curve was too sharp to be Lorentzian. In all instances the final limiting slope approached 1/f2. The resonance peak was observed in either Cl- or SO = 4 Ringer's but disappeared when Na+ was replaced with K+. Resonance frequency varied from 100 to 700 Hz.
面积小至0.07平方厘米的蛙皮钳制电流波动主要由低频成分（低于100赫兹）主导。在高密度氟硅油下对0.001平方厘米的膜片钳制显示出高达5000赫兹的成分，电流功率密度谱中通常包括一个峰值。导纳谱在相同频率处也有一个峰值。在一些蛙皮中未观察到峰值，但曲线的转折过于陡峭，不符合洛伦兹分布。在所有情况下，最终的极限斜率接近1/f²。在Cl⁻或SO₄²⁻林格氏液中观察到共振峰，但当用K⁺取代Na⁺时共振峰消失。共振频率在100至700赫兹之间变化。
