Abstract

An integrated photonic microwave bandpass filter has been demonstrated incorporating a coherently coupled microring resonator in low-loss polymers. The resonator was designed to have an extremely small bandwidth so that it could be used to selectively pass the optical signal carrying the microwave signal to attain efficient bandpass filtering. The demonstrated device may feature compact size, simple structure, stable operation, possible tuning via the thermooptic effect, and furthermore flexible integration with other electrical/opt ....etc

Abstract—
The aliasing signal interferes with the actual signal and resembles more-like the original intermediate signal. This is called image frequency. To eliminate this image frequency a filter is to be designed in the RF (Radio Front) stage. At S-band microwave frequency (2 GHz to 4 GHz), the lumped components cannot be used due to distributed effects. Also, for the compactness of the filter, the distributed components are being used in microwave frequencies. Hence the coupled stage of microstrip filter with g ....etc

The most important development in the computer communications industry in the 1990s is the evolution of the integrated services digital network (ISDN) and broadband ISDN (B-ISDN). The ISDN and B-ISDN have had a dramatic impact on the planning and deployment of intelligent digital networks providing integrated services for voice, data and video. Further, the work on the ISDN and B-ISDN standards has led to the development of two major new networking technologies; frame relay and asynchronous transfer mode (ATM). Frame relay and ATM have become t ....etc

Understanding and Diagnosing the ADS System
ADS is a fantastic system designed by MB to adjust the damping level of the shock absorbers to help stabilize the car during high speed driving, aggressive driving, or if the driver loses control of the vehicle. The 1995 S600 W140 is equipped with ADS II. Several changes were made to the original ADS system to make it even better than it was. I am still in the process of determining when ADS was introduced in Mercedes Benz cars. There are some sources on the internet that s ....etc

Abstract
This paper describes a single-chip CMOS quad-band(850/900/1800/1900 MHz) RF transceiver for GSM/GPRS applications.It is the most important design issue to maximize resourcesharing and reuse in designing the multiband transceivers. Inparticular, reducing the number of voltage-controlled oscillators(VCOs) required for local oscillator (LO) frequency generation isvery important because the VCO and phase-locked loop (PLL) circuitsoccupy a relatively large area.We propose a quad-band GSMtransceiver architecture that employs a direc ....etc

Abstract
The diagnosis system of Maglev Train is introduced in this paper. The system structure and diagnosis method are analyzed and discussed in detail. The disadvantages of diagnosis system are proposed. In virtue of the theory of ADS (Autonomous Decentralized System), some basic ideas of ADS are applied in new diagnosis system. The structure, component parts and diagnosis method of new diagnosis system are proposed, designed and discussed in detail. The analysis results show that new diagnosis not only embodies some ADSâ„¢ ideas but ....etc

WIDE RANGE BAND PASS FILTER
DESCRIPTION:
Third-Order Wideband Bandpass Filter
This circuit demonstrates the operation and characteristics of a wideband bandpass filter, constructed by cascading a second-order low-pass and a high-pass filter. As a result, a 300 Hz to 3 kHz bandpass voice filter is formed.
Experiments:
Set the function generator to 1 kHz and the oscilloscope's time base to 0.2 ms/DIV. Increase the input frequency, about 1 kHz at a time up to 4 kHz, constantl ....etc
