A method for analyzing at least one golf swing parameter using a plurality of accelerometers located proximate the distal ends of a golf club, a signal processing and display system utilizing a double pendulum model of a golf club swing, said model for describing swing parameters and having an upper portion, a pivot point and a lower portion, the method comprising the steps of entering initial swing conditions and golf club parameters; performing a swing and collecting data from the accelerometers; determining a differential mode signal from the acceleration data; calculating the pivot point location relative to each accelerometer using the accelerometer data; calculating a common mode signal using the pivot point; and determining at least one golf swing parameter as a function of time using the common mode signal. In a specific embodiment, the step of calculating the pivot point location relative to each accelerometer comprises the step of minimizing the contribution of the common mode signal into an accelerometer signal comprising the differential mode signal and the common mode signal. The method may also comprise the step of displaying the at least one golf swing parameter.
