  1. Wayne Ryder Electronic Design The prescaler described here connects to the front end of a 100-MHz frequency counter to extend its coverage range to 10 GHz. The circuit is a far less expensive way to measure frequencies above 100 MHz than buying a ...

  2. Lukas Fässler Some of you may have seen my arduino-based inductance meter in the article [1]. The arduino-based meter works well and made a great proof-of-concept. But for everyday use you’re probabely not looking for an ...

  3. Abel Raynus EDN Thermocouples find widespread use for temperature measurement in systems. During system design or testing, you must observe the system's response at different temperatures. However, it's inconvenient to heat a thermocouple ...
  4. W. Stephen Woodward EDN The accurate transmission of analog signals over long distances in noisy industrial environments is a difficult design problem. One of the oldest solutions isolated current loops is still one of the best. This Idea For ...
  5. Bill Reeve Electronic Design Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and characteristic curves. The ...
  6. Jim Williams Mark Thoren EDN Although quartz crystals have served as temperature sensors, designers haven't taken advantage of the technology because few manufacturers offer the sensors as standard products (references 1 and 2 ). In contrast to ...

  7. Wayne Sward EDN The circuit in Figure 1 efficiently monitors common digital-audio signals. One format for such signals is the Audio Engineering Society (AES) 44.1- or 48-kHz standard. Typically, the data consists of a serial data stream with a data ...
  8. Stephen Woodward EDN For at least four decades, dual-slope integrating A-to-D conversion has formed the core of most every digital multimeter and many industrial and instrumentation applications besides. Elegant in its simplicity, a DSADC ...

  9. Ken Whiteleather Electronic Design Current-mode control loops (particularly the popular 4- to 20-mA controls) are used in many industrial applications because of their immunity to induced EMI from motors, contactors, relays, and other sources. ...
  10. Clayton Grantham EDN Many process-control sensors, such as thermistors and strain-gauge bridges, require accurate bias currents. By adding a single current-setting resistor, R 1 , you can configure voltage-reference circuit IC 1 to produce a ...
