Abstract
Methods and devices for switching filters and medical apparatuses using the same are described. The method includes: detecting whether or not a frequency range of an input signal is changed from a first frequency range into a second frequency range; if changed, switching from a first filter to a second filter, and taking a sample value of the input signal at a current moment as an input value of the second filter at the current moment and sample values of the input signal at n moments before the current moment as input values of the second filter at the n moments, respectively, and taking output values of the first filter at m moments before the current moment as output values of the second filter at the m moments, to obtain an output value of the second filter at the current moment.
