Title:
METHOD AND DEVICE FOR COMMUNICATING SIGNAL PASSING THROUGH CAPACITOR
Document Type and Number:
Japanese Patent JP3872115
Kind Code:
B2
Abstract:

PURPOSE: To connect signals without using any large-scaled transformer or capacitor between more than two electric circuits operating with different voltages.
CONSTITUTION: A node 911 at a transmission side is connected through an aeries preventing filter 901 with a sigma/delta modulator 902, and a sigma/delta bit stream is generated, and supplied through a capacitor 909 to a digital sigma/ delta demodulator, and a digital output signal is supplied through a digital filter 904 to nodes 9 and 6. In this case, the data can be DSP-processed, impressed to a computer, or converted into an analog configuration. The compact capacitor 909 forms a high voltage barrier.
