Performance Evaluation of Four Wave Mixing & Optical Add Drop Multiplexer(OADM) in Optical Fibre Communication System
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 11 Optical fiber communication is the best for transmitting data at a high rate. While the fiber channel may be capable of transmitting terabit-per-second data rates, no existing single communication system can make complete use of this speed. Optical fibers in discussion that guide signals in the form of light are typically made of from two glasses. It is a cylindrical in shape waveguide c...

Design of 8-Bit Arithmetic Processor Unit based on Reversible Logic
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 10 Reversible logic is emerging as an important research area in the recent years due to its ability to reduce the power dissipation, which is the main requirement in low power digital design. Energy dissipation is proportional to the number of bits lost during computation. The reversible circuits do not lose information and can generate unique outputs from specified inputs and vice versa. ...

Electric Theory of Tornado. Protection from Tornado
Published In: GJRE Part: F: Electrical & Electronic Volume: 13 Issue: 14 The author develops a new theory of tornado stability. He show that it is the high electric voltage between clouds and ground surface which produces the intensive electron/ion flow which creates the air stream which sucks off (pumping) air from the inside tornado channel and makes the tornado stable. If we want to destroy tornado stability we must decrease the electric intensity into the...
