The Ideal Filter In Just Six Steps

Every developer of an electrical or electronic device is faced with the same problem: in the end, the device must comply with international EMC guidelines regarding emissions and immissions. In the age of the substitution of mechanical and mechatronic systems by purely electrical ones, EMC is becoming increasingly important.

Besides small SUVs, crossovers are also filters used in audio to divide the audio signal into two or more frequency bands. A typical example is a home cinema audio system where a subwoofer handles the low bass frequencies while other speakers handle the mid and high frequencies. Here is an active 3-way crossover design with three or four stages based on state-variable filters.

Toshiba has developed an image recognition technique that allows depth information to be derived from the output data of a single image sensor, in addition to a color image. The new technique provides excellent depth/range detection, comparable to that of a stereo camera.

Anonymous phone call reject circuit: Made for POTS analogic phone lines, this circuit analyses the Caller Identifier data (CLIP) sent between the two first call rings of incoming phone calls, rejecting any P (Private) or O (Out of area) calls types. Fully tested in Europe. No batteries required: It takes energy directly from the phone line, surging less than 1 mA.

A while back we made a little break-out-board with a ADS1115 A/D converter (140169-1). It has four inputs that can be used in a single-ended mode or two inputs can be used in a differential mode. A project still in development is a power meter for mains powered appliances.

When considering the design of a filter, one is inclined to think of a combination of inductors, resistors, and capacitors, perhaps in association with an active element. The filter in the diagram shows that a different approach is perfectly feasible.
