  • Double Glazing Banbury - Double Glazing Windows And Heat Loss
    By: kenu2jueca | - Heat loss comes with a impact in energy bill and ultimately your carbon footprint. Installing double glazed windows could save you 165 per year (using B-rated windows at least). Naturally you'll be using less energy (less fuel) therefore the quantity of generated carbon dioxide will probably be reduced too. The windows are constructed with two layers of glass using a relatively smaller than average air gap between.

  • Techniques For Accurate Electrical Charge Measurements
    By: Johnathan L Tucker | - Charge is often measured as a quantity of particles on a physical surface or stored in a capacitor. Often, the human body, an electronic cable, or other electrical components may have a certain amount of inherent capacitance that allows charge to be stored on their surfaces. It can be important to know the quantity of this charge in order to understand the nature of an electrostatic discharge (ESD) waveform (voltage and current) when the charge is transferred to electronic circuitry. This allows ...

  • Triax Cables Can Improve On-wafer Parametric Testing
    By: David Rose | - In wafer level DC measurements, anticipating the signal magnitudes makes it easier to assess potential sources of error. For simplicity, let"s assume all of the signals being measured are neither high voltage (i.e., greater than 100V) or high current (greater than 200mA). We can break down the error sources into four categories: leakage currents, electrostatic interference, mechanical effects, and test lead resistance.

    Leakage currents. These are currents flowing through paths ...

  • How To Compute Snr Or Signal To Noise Ratio
    By: Jim Meer | - The SNR or Signal to Noise Ratio gives a contrast of the signal amount w/ the background noise amount in a specific signal; such that a high Signal to Noise Ratio specifies the noise is less obvious. The Signal to Noise Ratio is utilized in electrical engineering where the signal is electromagnetic, but it has uses in acoustics as well, where the signal is known as a sound. The decibel is described in a way that the Signal to Noise Ratio can be applied to every signal, in spite of its source.
