Printer Port Records Digital Waveforms -  06/18/98 EDN Design Idea   (File includes several circuitsscroll to find this one)  To record or capture special waveforms, thOse that appear once or have no fixed frequency, the usual technique is to use a logic analyzer or a storage OscillOscope. However, these tools are very expensive. Moreover, because of limited memory, a storage scope can record fewer than 1000 samples. The technique presented here provides an alternative method to recording digital waveforms. The idea is to use the PC's printer port to sample waveforms, and the PC's memory to store data. . . .  [by Dean Shen, Dycam Inc, Chatsworth, CA] 

 

PScope: High-Speed ADC Data Collection Software -  When provides a customer with a high speed ADC demo board we also provide PScope, the software to evaluate the demo board. PScope is a simple software package that can collect, and display data from high speed ADC demo boards. It will also provide a simple and easy way to measure the key performance parameters . . .  [Linear Technology App Note - , Clarence Mayott Jan 4th 2011]

Remote digital thermometer sends data over AC power line -  This circuit is a simple Oscillator. It's frequency is in the range 35 kHz - 60 kHz and it' s adjustable. . . .  [by Ali Alipour.r - alipoor90 @ gmail.com]

 

Remote Digital Thermometer Sends Data over AC Power Line -  This circuit is intended for precision centigrade temperature measurement, with a transmitter section converting to frequency the sensor's output voltage, which is proportional to the measured temperature. The output frequency bursts are conveyed into the mains supply cables. The receiver section counts the bursts coming from mains supply and shows the counting on three 7-segment LED displays. The least significant digit displays tenths of degree and then a 00. 0 to 99. 9 °C range is obtained. Transmitter-receiver distance can reach hundred meters, provided both units are connected to the mains supply within the control of the same light-meter. . . .  [Flavio Dellepiane's web site]

 

Resonant Approach to Designing a Band-Pass Filter for Narrow-Band, High IF, 16-Bit, 250 MSPS Receiver Front End  -  The modified AD9467-250EBZ board contains the circuit evaluated as described in this note, and the HSC-ADC-EVALCZ data capture board is used in conjunction with VisualAnalog evaluation software, as well as the SPI controller software to properly control the ADC and capture the data.

RS-232C handshake lines transfer data frame -  10/23/97 EDN Design Idea   The asynchronous RS-232C interface is a simple, low-cost option for interconnecting processor-based systems, but this character-oriented interface supports no direct mechanism to transfer variable-sized messages as self-contained. . .  [by SK Shenoy, Naval Physical & Oceanographic Lab, Kochi, India]
