Simple FIFO provides data width conversion -  26-Sep-02 Issue of EDN  Many designs require FIFO elastic buffers to form a bridge between subsystems with different clock rates and access requirements. However, in some applications, you need FIFO buffers for data conversion. One example is the case in which you need to connect an 8-bit ADC to a 16-bit data-bus microprocessor through a FIFO buffer (Figure 1].....

Simple Logic Probe uses Bicolor LED -  03/13/98 EDN Ideas.....A project posed the challenge of replacing existing analog potentiometers (used to set brightness and contrast levels]in video monitors with digitally controlled potentiometers. The different brands and models of monitors presented widely varying voltages across the potentiometers. The design….PDF has several circuits, scroll to this one..... [Design Idea by Mark Shill, Burr-Brown Corp, Tucson, AZ]
Simple Logic Reduces Emi -  08/05/99 EDN-Design Ideas.....A current-input ADC whose primary use is measuring low-level signals from photodetectors can also measure a range of voltages using the circuit in Figure 1. The main component is a dual-input current-integrating ADC, IC1. IC2 and IC3 provide the buffered 4.096V reference for IC1..... EDN is migrating links.

Simple Low Cost Digital Code Lock -  .....
Simple setup tests-bit error rate -  18-Mar-04 Issue of EDN  Traditionally, the reception quality of a digital receiver is expressed in terms of BER (bit-error rate].  This figure is the proportion of received bit errors in a given period. Typically, you measure the BER in the lab by applying an RF signal, modulated by a pseudorandom code, to the receiver under test.....

Simplifying External Memory Connections of PIC17cxxx Picmicro ® MicroControllers -  Microchip Application Note Published 23-Aug-99  (app note added 2/06)
Single switch controls digital potentiometer -  7-Feb-02 Issue of EDN  The control of electronic potentiometers in most today's applications comes from controller-generated signals. However, a significant number of applications exist that require adjustments using manual, front-panel controls. The circuit in Figure 1 uses one IC, one switch, and 10 discrete components..... [Design Idea by Chuck Wojslaw and Gary M Craig, Catalyst Semiconductor, Sunnyvale, CA]
Single-switch controls digital potentiometer -  19-Sep-02 Issue of EDN This Design Idea is an evolution and simplification of another (Figure 1, Reference 1]. Replacing the three inverted-input NOR gates with their logical equivalents, positive-input NAND gates, makes these three gate symbols consistent with the fourth, which was drawn as a positive-input NAND gate. The 74HC132's data sheet describes the device as a quad, two-input NAND gate with hysteresis.....[Design Ideas by Jim Bach, Delphi Delco Electronics Systems, Kokomo, IN] [Design Idea by im Bach, Delphi Delco Electronics Systems, Kokomo, IN]
