An alternating current polargraph (fundamental and second harmonic) has been constructed using operational ampliers.
This instrument is capable of phase sensitive detection and phase angle detection at the frequency of 70,140,280,560,1120Hz respectively.
The AC and cyclic voltammogram of cd²+ show that this instrument could be applied to measure electrochemical onalysis and reaction.
