Enabling digital microphones Design How-To 8/8/2007 1 comment Next-generation microphones capable of increased performance are required to address the needs of mobile phones. This article gives an overview of the issues, and describes a microphone preamplifier that enables the design of a digital-output microphone for the mobile microphone market.
Audio amp design: Do you tube? Audio DesignLine Blog 8/7/2007 Post a comment Vacuum tubes had been relegated to the history books by the time I studied engineering. Had it not been for my interest in audio - and high-end audio in particular - I might never have experienced the fascinating world of tube audio design.
Transmitters measure pressure up to 25 bar Product News 8/2/2007 Post a comment Aktiv Sensor, an EPCOS subsidiary, has developed a new series of precision pressure transmitters that is designed for measuring absolute and relative pressure in the range between 100 mbar and 25 bar.
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
