Features of binary-encoding method (BEM); Comparison between BEM and OHE; State-machine types; Description of the OHE macros; Effect of OHE on closed-loop applications; Functions of the OHE macro.

In this article, the author discusses ways to operate properly programmed binary-coded decimal (BCD) real-time clock (RTC) chips. It mentions that RTC counter chains can be found in many BCD-formatted RCTs and each counter register has defined minimum and maximum values. It illustrates a date register BCD count sequence for a 30-day month.

The article focuses on the use of four-pin Zetex ZXCT1010 current-sense monitor chip and metal-oxide-semiconductor field-effect transistor (MOSFET) in boosting output current. A figure is presented to demonstrate how a MOSFET and a current sense monitor can increase load current by bypassing binary-coded-decimal (BCD) switches. Also discussed is an equation which can be applied when calculating the four weighting resistors of BCD switches.

The article offers information concerning the requirements needed in constructing a programmable current source circuit. It states that the circuit uses three sections of binary-coded-decimal (BCD) switches, a National Semiconductor LM317 three-terminal adjustable regulator and a handful of 1%-tolerant resistors. It emphasizes that current source can be constructed by using a heat sink for the LM317 or by building the circuit into a diecast aluminum housing.

The article proposes an easy-to-build, easy-to-use, low-cost current source that is useful for creating input voltage (I-V) curves, charging and discharging batteries, preloading power supplies and many other applications. The circuit comprises three sections of binary-coded-decimal (BCD) switches, a three-terminal adjustable regulator, a handful of 1%-tolerant resistors and a National Semiconductor LM317 three-terminal adjustable regulator. The article also offers information on how the circuit operates.

The article focuses on a C/C++ program that converts decimal numbers ranging from 0 to 99,999 to binary and BCD formats. Using a simple algorithm in conjunction with pointer arithmetic and bitwise shifting increases the conversion speed without introducing excessive memory overhead and programming complexity. When decimal numbers are within the range of 0 to 9, their binary and BCD representations are identical, requiring only four bits (0000 to 1001). When the numbers are within the range of 10 to 19, the binary representation varies between four and five bits, such as 1010 to 10011. The BCD representation uses eight bits, such as 0001 0000 to 0001 1001. If one treats the BCD representation as a straight binary number and compare it to the actual binary representation of the decimal value, we note that there's a decimal difference of 6 between the two numbers.

The article presents a glossary on computer hardware terms. A bit is a single digit in a binary number, or a physical memory cell within a computer memory. The Complex Instruction Set Computing is a conventional microprocessors that have many built in instructions. Floating-point accelerator is a circuitry designed to speed up floating-point operations per second.

A reprint of the article "Conversion Circuit Handles Binary or BCD" which appeared in the April 5, 1979 issue of "Electronics Design, Strategy, News" is presented. A circuit that can perform binary and binary-coded decimal (BCD) conversions is described to use up/down counters to get the desired results. A binary to BCD conversion is cited to be achieved by presetting the binary value in the binary counter and clearing the BCD counter.

The article explains how to perform hexadecimal-to-binary-coded-decimal (BCD) conversion in microcontroller firmware. The programming technique for the conversion, which can add-three algorithm, is described. Also detailed is the reason all registers for hexadecimal and BCD digits should reside consecutively in memory. An overview of the conversion process is presented.

The article demonstrates how delta-sigma converters use many samples from the modulator to produce a stream of 1-bit codes. The delta-sigma analog-to-digital converter (ADC) accomplishes this task by using an input-signal quantizer running at a high sample rate. Like all quantizers, it takes an input and produces a stream of digital values that represents the voltage of the input. A time-domain representation is presented in order to illustrate the mechanics of a first-order modulator which measures the difference between the analog-input signal and the analog output of a feedback digital-to-analog converter (ADC).
