Four Quick Steps to Production: Using Model-Based Design for Software-Defined Radio

Part 3—Mode S Signals Decoding Algorithm Validation Using Hardware in the Loop

This month we present Part 3 of our ongoing series on software-defined radio, covering validation of the system algorithm using live data as input and some powerful software and system development tools provided by ADI, MathWorks, and Avnet. If you’ve read Parts 1 & 2, you’ve seen this SDR system steadily progress from initial prototyping toward a production design.

Versatile, Precision Single-Ended-to-Differential Signal Conversion Circuit with Adjustable Output Common Mode Boosts System Dynamic Range

This article revisits an earlier design of a versatile, low power single-ended–to–differential converter circuit. This time around, this useful converter circuit is made even more versatile. The authors have addressed using the circuit in applications that require greater output dynamic range, such as in signal conditioning of temperature and pressure sensor outputs.

If grounding is one of the most common causes of analog problems, what is the next most important?


Four Quick Steps to Production: Using Model-Based Design for Software-Defined Radio

Part 2 — Mode S Detection and Decoding Using MATLAB and Simulink

The series on model-based software-defined radio system design continues toward the ultimate objective of building a platform that will receive and decode the automatic dependent surveillance broadcast (ADS-B) transmissions from commercial aircraft. This month our designers analyze the Mode S Extended Squitter format used in ADS-B signal transmissions and demonstrate how to capture these Mode S signals with a receiver platform based on the AD9361 RF agile transceiver IC.

Using ESD Diodes as Voltage Clamps

When external overvoltage conditions are applied to an amplifier's input, ESD diodes are the last line of defense between the amplifier and the catastrophic damage that can result from electrical over stress. In this article our expert shows us how ESD cells are implemented in an amplifier device, discusses their characteristics, and explains how they can be used to improve the robustness of a design.
