    Abstract: PROBLEM TO BE SOLVED: To reduce collision between a pedometer function and functions except the pedometer function. SOLUTION: An inertial device that is integratable in a portable electronic device includes: an inertial sensor (11) for generating at least one raw acceleration signal (S X , S Y , S Z ) in response to acceleration caused by movement of walking and running of a user of a pedometer; and a processing unit (12), associated to the inertial sensor (11) for counting the number of steps (N T ) of the user of the pedometer on the basis of the raw acceleration signal (S X , S Y , S Z ). The inertial sensor (11) and the processing unit (12) are both encapsulated within a single package for integrated circuits (13), which can be coupled to a circuit board (9) of an electronic device (1) and is provided with at least one connection terminal (13a) for making the number of steps (N T ) available to the outside world.

    Abstract: A digital high-pass filter (12) has an input (IN), an output (OUT), and a subtractor stage (20), having a first input terminal, a second input terminal and an output terminal. The first input terminal of the subtractor stage (20) is connected to the input (IN) of the digital high-pass filter (12) and the output terminal is connected to the output (OUT) of the digital high-pass filter (12). A recursive circuit branch (21) is connected between the output (OUT) of the digital high-pass filter (12) and the second input terminal of the subtractor stage (20). Within the recursive circuit branch (21) are cascaded an accumulation stage (23), constituted by an integrator circuit, and a divider stage (24). The cutoff frequency (f t ) of the digital high-pass filter (12) is variable according to a dividing factor (den) of the divider stage (24) .
