the speaker. Resistor R6 is meant for protecting the transistor when R4 is turned towards low resistance values. Resistor R2 and R1 forms a feedback network for the TDA2002 and C1 couples the feed back signal from the junction of R1 & R2 to the inverting input of the same IC. The diode D1 and D2 in combination drops 1.4 V to give the rated voltage (3.5V ) to UM66. UM66 cannot more than 4V. CIRCUIT DIAGRAM Power supply for the circuit. A well regulated power supply is

CHAPTER - 1 INTRODUCTION 1.1 STATE OF ART Photovoltaic (PV) generation is becoming increasingly important as a renewable source since it offers many advantages such as incurring no fuel costs‚ not being polluting‚ requiring little maintenance and emitting no noise among others. But still‚ these modules have relatively low conversion efficiency due to their nonlinear and temperature-dependent voltage-current and voltage power characteristics. Power generated by PV generators and injected into the

instead of radiowaves and microwaves. The most commonly used scheme for VLC is intensity modulation (IM) and direct detection (DD). In VLC systems with intensity modulation (IM) and direct detection (DD)‚ the modulation bandwidth of light emitting diode (LED) is limited‚ and the dispersion of the channel might cause ISI. Therefore most modulation schemes cannot be used directly for such a system. This project aims to show that a multiple-input multiple output (MIMO) orthogonal frequency division

single Si nanowires‚ by means of microphotocurrent spectroscopy combined with transport measurements of carrier diffusion length using the electron beam induced current technique. The study is performed on different diameter nanowires with Schottky junctions created by doping modulation during Chemical Vapor Deposition–Vapor Liquid Solid growth. We show that the photocurrent spectra of single Si nanowires do not follow monotonous profiles as bulk silicon‚ but rather have steep valleys and peaks whose
