Title: Method and system for providing a linear signal from a mass airflow and/or liquid flow transducer

Abstract: A method and system for providing a linear signal from a flow transducer. A non-linear raw signal can be obtained from a mass flow transducer. An approximated error comprising a discrete sinusoidal function incremented by a variable and selectable omega value can then be subtracted from the non-linear raw signal, in order to provide a subtracted result and reduce an error range thereof. The linear signal can then be obtained from the subtracted result in order to linearize a raw output from the flow transducer. A user is thus permitted to tune a frequency increment associated with the variable and selectable omega value in order to reduce the error range thereof. Linearized airflow and liquid flow sensor outputs can thus be generated by allowing a user the freedom to tune the frequency increment depending upon the user's flow range for reducing errors.
