Abstract

The invention provides a method and a device for waveform analysis. The method includes that sinusoidal waveforms are received and sampled to obtain square waveforms, and the square waveforms sequentially include waveforms of test data and waveforms of valid data; a pulse width Mi between an i rising edge and a (i+1) rising edge in the waveforms of the test data is obtained, and a pulse width Ni between an i falling edge and a (i+1) falling edge in the waveforms of the test data is obtained; a cycle T0 of logic 0 and a cycle T1 of logic 1 are obtained by the pulse width Mi and the pulse width Ni; whether the pulse width Mi and the pulse width Ni are between the cycle T0 and the cycle T1 or not is determined; if the pulse width Mi is between the cycle T0 and the cycle T1, bits represented by the waveforms of the valid data are analyzed in sequence according to a pulse width between two adjacent falling edges in the square waveforms; if the pulse width Ni is between the cycle T0 and the cycle T1, bits represented by the waveforms of the valid data are analyzed in sequence according to a pulse width between two adjacent rising edges.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for analyzing waveforms. Background technique [0002] The smart key device is a security device with signature function and / or dynamic password generation function. When the smart key device communicates with mobile terminals such as mobile phones and tablet computers through audio interfaces, after the mobile terminal outputs waveforms, the smart key device will sample the received waveforms and analyze the bits corresponding to the waveforms.
