  1. Frequency Quadrupler Enables Low-Frequency Measurements, Spans Up To Four Decades
    Measurement Texas Instruments CD4070B, CD4093B, CD40106B, LM339A, LMV324
    David Conrad Electronic Design The challenge in measuring low frequencies is that the counter gate time is often too short for the signal relatively long period. This non-critical circuit automatically multiplies an input single frequency times ...

  2. Convert voltage to potentiometer-wiper setting
    Measurement ON Semiconductor CAT5114
    Chuck Wojslaw EDN The circuit in Figure 1 converts an analog input voltage, V IN , to a proportional wiper setting of a DPP (digitally programmable potentiometer). The potentiometer's wiper setting, which varies from position 0 through 31, ...

  3. Add a signal-strength display to an FM-receiver IC
    Wireless Measurement NXP TDA7000
    Jose Miguel-Lopez EDN The TDA7000 integrates a monaural FM-radio receiver from the antenna connection to the audio output. External components include one tunable LC circuit for the local oscillator, a few capacitors, two resistors, and a ...

  4. Use Inexpensive Components To Create An Infrared Close-Object Alert Circuit
    Automation Measurement Robots Texas Instruments LM555, CD4060B
    T.K. Hareendran Electronic Design Many robotic applications require a sensor to detect close or very close obstacles. Typically, reflective-type infrared sensors are used for this task. But the circuit in the figure 1 shows an infrared close-object ...

  1. Pseudologarithmic thermistor signal conditioning spans wide temperature range
    Analogue Design Measurement
    Stephen Woodward EDN Given its low cost, small size, robust construction, accuracy, versatility and sensitivity, it's no wonder that the thermistor rates as one of the most popular temperature sensors available. However, in some applications, a ...

  2. Current-mode instrumentation amplifier enhances piezoelectric accelerometer
    Analogue Design Measurement Texas Instruments INA121, TL081
    Dave Wuchinich EDN A typical piezoelectric sensor comprises a disk of PZT-5A ceramic material with metallized electrodes on its surfaces. Applying electrically conductive epoxy to the electrodes connects external wiring to the sensor. An insulating ...

  4. 10-GHz Divide-By-100 Prescaler Connects To 100-MHz Counter
    Measurement Analog Devices HMC361, HMC438
    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 ...

  6. Network imitates thermocouples
    Analogue Design Measurement
    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 ...
