<P>PROBLEM TO BE SOLVED: To provide an electrocardiograph signal processor, capable of surely eliminating power supply frequency synchronous noise and having a small-sized and inexpensive noise filter. <P>SOLUTION: This electrocardiographic information reporting system includes palmus detecting electrodes 31, 32, 33 set in the bathtub B for detecting an electrocardiograph signal of a bathing person, a heart rate computing unit 40 for calculating the heart rate of the bathing person according to the electrocardiograph signals detected by the palmus detecting electrodes 31, 32, 33, and an operating remote controller of a bath hot water supply device for displaying the bathing person's heart rate created by the heart rate computing unit 40. The heart rate computing unit 40 is composed of a band elimination filter 43a and a secondary low pass filter 43b. The band elimination filter 43a has frequency characteristic of showing a sudden damping in a frequency band area between the central frequency and a cutoff frequency of the low-pass filter 43b. <P>COPYRIGHT: (C)2003,JPO |
