摘要： Systems, methods, and devices for generating multiple cyclic square-waveforms and sloped-edge square waveforms. Aspects of the techniques disclosed herein include applying the generated waveforms to an electrode used in voltammetry, e.g., to measure a level of a neurochemical in neural tissue. An electrode can be located in a solution, and an electrical stimulus applied to the solution through the electrode using a multiple cyclic square waveform. An electrical current response to the stimulus is measured, and a level of an analyte (e.g., dopamine or other neurochemical(s)) determined based on the electrical current response.
