WebA common mode choke is an electrical filter that blocks high frequency noise common to two or more data or power lines while allowing the desired DC or low-frequency signal to pass. Common mode (CM) noise current is typically radiated from sources such as unwanted radio signals, unshielded electronics, inverters and motors. WebFilters implemented with these elements are termed 'switched-capacitor filters'. Unlike analog filters, which must be constructed with resistors, capacitors and sometimes inductors whose values are accurately known, switched capacitor filters depend only on the ratios between capacitances and the switching frequency.
Electronic filters can be classified by the technology used to implement them. Filters using passive filter and active filter technology can be further classified by the particular electronic filter topology used to implement them. Any given filter transfer function may be implemented in any electronic filter topology. … See more Electronic filters are a type of signal processing filter in the form of electrical circuits.
