The use of metal microelectrodes in broad-band recording.
We checked to what extent the voltage-current relationship of a microelectrode is linear. In the linear domain we measured the impedance characteristic of the electrode. We measured the frequency response curve and the phase characteristic of the electrode and amplifier system.
