    The main focus of this idea is the reduction of harmonics and subharmonics of a software realized digital amplitude limiter. In RF base stations where the modulation devi- ation has to be limited, it is important to minimize harmonics which can influence the neighbour channels.

    A SIDAC is a high power breakover diode. It diverts lightning surges away from sensitive elec- tronic components when used as a transient sup- pressor in telephone applications. Lamp starters use the device to generate the high starting voltage pulse. These applications result in turn-on switching stress because of...

    Call waiting is a supplementary service which existing PSTNs already provide for wire-line phones and mobile phones. If the telephone subscribes to this service and if there is an incoming call while the telephone is busy, in-band signalling in the form of short beeps are introduced into the voice channel of the...

    A key capability required for the effective man- agement of software development organizations is the ability to accurately estimate the effort] required to produce a sollware product. Automated tools exist to aid in this estimation process, but of those tools currently available, none provide the user with any data...

    In the design of VLSI circuits and systems the need frequently arises for signals having prescribed standard waveforms with specified characteristics like amplitude, frequency and duty cycle. These stand- ard waveforms, which include sinusoidal, square, tri- angular, pulse, and etc., can be generated in Signal...

    The maximum length for telephone intercon- nect calls is set by the trunking system controller in relation to the amount of system activity. The radio operator has no input in this decision and can become dissatisfied if the length of an important call is lim- ited or if the call is prematurely terminated. Fur- ther,...

    Currently, scanning pagers have one way com- munication only and there is no capability of auto- matically tracking pager location. Therefore, either duplicate messaging or user identification of current location is necessary. If these tracking requirements are not met, transmitted pages are lost during transit from...

    SOLUTION To achieve high quality solder paste printing proc- ess, board retention (i.e. vacuum) and support are vital during the printing process. These three objec- tives are easily achieved when printing single sided boards or the first side of double sided boards, as the under side of the board is flat and can...

    An image sensor having a portrait orientation includes an array pixels having n columns and m rows. The portrait orientation includes each column having a significantly greater number of pixels than the number of pixels in each row so that, when in its normal orientation, the vertical height of the image sensor is...
