These include an aperture for the sunlight to pass through, absorbers and thermal mass to absorb and retain the heat, distribution for heat circulation, and a fixed control that will provide shade during the summertime. Apertures The apertures, or collectors, in passive solar buildings, are often...
Also, the examples typically use a low-pass filter to attenuate DAC output images before they go into the IQ modulator. For band-pass filters, a pullup network on the modulator side is needed to replace the filter termination and provide the modulator with its required common-mode voltage. ...
Let’s now talk briefly about wire-wound resistors, often chosen because they have very low temperature coefficients (tempcos). These resistors also have an important, unique characteristic: its structure can react to magnetic fields. Because they are essentially a coil of wire, they magnify a m...
3. Integrator or Calculator (optional)--Rapid and accurate calculation can be performed with the help of an electronic integrator or calculator. This must give a linear response with adequate sensitivity, and baseline correction should be consistent with good chromatographic practice. Horizontal, non-...
