Case Study 1: Mixed-Signal Focus

With a contribution by

Scott Cooper,     Mentor Graphics Corporation

This first case study introduces the radio-controlled airplane system that will be thoroughly analyzed throughout the five case studies presented in this book. In this case study we focus on the encoding, transmission and decoding of the analog throttle and rudder command signals as they make their way to their respective end effectors. This portion of the system constitutes the “command and control” electronics for the airplane. We emphasize analog-to-digital (A/D) and digital-to-analog (D/A) signal conversions to illustrate mixed-signal modeling with VHDL-AMS.

As noted in the Preface, the case studies ...
