  1. by Shyam Tiwari EDN The need for a compact telemetry system poses a challenge for designing a small, light, low-component-count system. Interfacing serial data from the microprocessor is also difficult because most low-cost RF transmitters do not ...

  2. Raju Baddi EDN When designing logic for higher-than-usual supply voltages, such as 24 V, you can use a voltage regulator with a standard logic family and interface it through level shifters. Alternatively, if the logic is not too complex and the ...

  3. Anthony Smith EDN Converting band-limited NRZ (non-return-to-zero) data to a digital format suitable for microprocessors and other digital systems poses problems when a signal's duty cycle or amplitude varies or when its average level ...

    Maxwell Strange EDN Figure 1 is the block diagram of an easily programmed, single-button combination lock. You operate the lock by using a series of short and long pulses from a momentary switch that masquerades as a doorbell button. The circuit ...

    Steve Hageman EDN To test products in my R D lab, I build many universal data-acquisition systems that connect to a PC or another controller through RS-232 links or LANs. These small systems typically include multiple ADC, DAC, and digital-I/O ...

  2. Santosh Bhandarkar EDN A simple and inexpensive electronic circuit uses a low-cost pushbutton switch to toggle the electrical power on and off. The circuit replaces a more costly and bulky push-push mechanical switch. The pushbutton switch triggers ...

    Bob Marshall EDN In new mixed-voltage systems, it is often necessary to level-shift a control signal from a high level to a low level. An open-drain device, such as the 74LVC2G07 , easily performs this shift. However, when a bidirectional signal ...

  4. Michael Whybray EDN Most desk fans I have come across have three speeds: Full Speed, Almost Full Speed, and Off useless if you want just a gentle air movement, and far too noisy if you are trying to get to sleep (in your bedroom of course, not at ...

  5. Circuits Digital Fairchild NC7SZ57 NC7SZ58
    Glen Chenier EDN You can assemble a pulse-generation circuit from a simple Schmitt-input AND gate plus a resistor-capacitor timing network. However, if you need a logic function that's not a standard catalog item, you need a Schmitt-input gate ...

  6. Karen Hunsberger Electronic Design This frequency upconverter circuit is a simple alternative to doing period measurement or accepting long latency when measuring very low frequencies, on the order of one to 100 Hz. Engineers occasionally need to ...
