An overview of generation schemes for picosecond pulses in the mid-infrared (2-10 microns) will be presented.

Abstract: Recent advances in high-speed optical characterization are reviewed.

In obtaining long life in telephone equipment such as relays, switches, selectors and other mechanical devices subject to large momentary forces, one of the main problems is the wear encountered in

Radio Astronomy has been a field which depended heavily on new technology for advances.

Data structures are the heart of many computer algorithms.

Suppose a network is constructed by connecting in an arbitrary manner any number of transistors, diodes, resistors, and independent voltage and current sources.

Three new systems, working on 3 mm. (4 mm. in one case) open line intermediately loaded have been giving satisfactory service in Norway for a year, and two more systems are being installed.

The initial development of the No.

This paper reports a novel voltage and current waveform measurement system suitable for large-signal transistor and power amplifier characterization and optimization.

All AT&T products, whether large switching systems (5ESS TM), sophisticated transoceanic optical fiber transmission systems (TAT8) or household telephones, are designed to fulfill customer expe
