Robust Design (Taguchi Method) Case Studies

Robust Ground to Air Communication Receiver Case Study FM data demodulator is a critical part of ground to air communication receivers used in aircrafts. It should be designed to minimize the bit error rate (BER). The main concept of demodulation is to convert the received RF signal to baseband voltage signal, sample it at the…

Design of Experiments for Software Testing

When DOE (design of experiments) is used for software testing, there is a large amount of savings in testing time and cost. Various users in automotive, telecommunication and defense industries report big productivity improvements to their traditional testing methods. This success is due to two major important factors: 1) focused attention on the usage of…

Introduction To Robust Design (Taguchi Method)

Robust Design method, also called the Taguchi Method, pioneered by Dr. Genichi Taguchi, greatly improves engineering productivity. By consciously considering the noise factors (environmental variation during the product’s usage, manufacturing variation, and component deterioration) and the cost of failure in the field the Robust Design method helps ensure customer satisfaction. Robust Design focuses on improving…
