  • TC7136/TC9400 Digital Readout Frequency Meter
    Two low-cost integrated circuits can be combined to create a simple digital frequency meter. The combination of a frequency-to-voltage converter (FVC) and a dual-slope, analog-to-digital display converter (ADC) makes a small 2-chip frequency meter that can be run from one 9-volt battery

    , and can provide digital measurement data to several decimal places in dBm or watts. But if they are so accurate, why is it so difficult to make good measurements? If you are making the most common mistake, correcting for it will dramatically improve your measurement accuracy. For the most common power

  • F-22 and F-35 Suffer From Network Gaps
    electronically scanned array (AESA) radars deliver sub-meter resolution. Much-improved electronic combat subsystems using digital radio-frequency (RF) technology can identify and locate emitters in ways that a few years ago were confined to large, special-purpose, electronic-surveillance measures
