Automatic College Bell System Using Labview,Arduino and Soundcard

By using Labview's graphical interface we can easily make a better interface for defining time,and Arduino as a external hardward will be better choice. You know how to interface arduino and labview , if don't better to read my previous posts. ................

Hybrid Operational Amplifier

we have generally confined our discussions and design examples to the basic 741 and the MC741SC. These devices are certainly not the newest, fastest, or necessarily the best in all applications, but they are very common and the principles presented directly extend to other higher-performance devices. To provide the reader with a dramatic performance contrast, and to illustrate the performance characteristics that are available in op amps, we will briefly examine the operational characteristics of a hybrid op amp manufactured by the M.S. Kennedy Corporation (MSK). Numerous devices manufactured by MSK offer outstanding performance. We will describe the MSK 739 Wideband Amplifier as a representative device.

Special Devices

PROGRAMMABLE OP AMPS

One class of specialized op amp is the micropower programmable op amp. Such devices utilize an external resistor to establish the quiescent operating current for the internal stages. That is, the internal stages are biased at a particular operating current by the selection of an external resistor. Several characteristics of the amplifier are altered by changes in the programming current (JP):
