if transceiver
A transceiver consists of a receiver and a transmitter. The architecture and key characteristics of different types of receivers and transmitters are covered in this chapter, helping the designer to choose the optimum for a specific application. The main function of a receiver is the demodulation of a wanted signal in the presence of undesired […]
iir filter
IIR filters are digital filters with infinite impulse response. The primary advantage of IIR filters over FIR filters is that they typically meet a given set of specifications with a much lower filter order than a corresponding FIR filter. Although IIR filters have nonlinear phase, Suppression of baseline wander and power line interference in ECG […]
image sensor
an electronic device that converts an optical image into an electronic signal Development of a mote for wireless image sensor networksfree download AbstractThis paper presents the design of a new mote for distributed image sensing applications in wireless sensor networks. The processing and memory limitations in current mote designs are analyzed and a simple but […]
inductor
An inductor, also called a coil, choke or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. An inductor typically consists of an insulated wire wound into a coil around a core. The design, modeling and optimization of on-chip inductor and transformer circuitsfree download […]
frequency synthesizer
frequency synthesizer allows the designer to generate a variety of output frequencies as multiples of a single reference frequency. The main application is in generating local oscillator (LO) signals for the up- and down-conversion of RF signals. A Σ- Fractional-N Frequency Synthesizer using a wideband integrated VCO and a fast AFC technique for GSM/GPRS/WCDMA Applicationsfree […]
fir filter
A finite impulse response (FIR) filter is described by the mathematical equation where h_k are the filter coefficients, and x(n-k) refers to past samples of the input data. Here x(n) is a set of values corresponding usually to samples of some physical quantity. For example, this could be samples of an audio waveform On the […]
gas sensor
gas detector is a device that detects the presence of gases in an area, often as part of a safety system. This type of equipment is used to detect a gas leak Gas Sensor module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke […]
hot swap controller
Hot Swap controllers allow electronic circuit boards and cards to be inserted into live system backplanes, eliminating the need to power them down. Mission critical systems, such as servers and communication equipment, operate continuously as boards are hot plugged in or pulled out, either for system maintenance an N-channel MOSFET that serves as the main […]
demodulator
A symmetric 3 3 coupler based demodulator for fiber optic interferometric sensorsfree download ABSTRACT A method for demodulation of fiber optic interferometric sensors that utilizes a 3 x 3 coupler is described. The passive demodulation scheme does not require carrier (phase) modulation. The demodulation scheme relies on the three outputs of a 3 x 3 […]
