A novel second order log-domain lowpass (LP) filter based on integrator loops and grounded capacitors is presented. The circuit uses nonlinear nature of the transistor, thereby acquiring wider dynamic range at low power supply, higher frequency operation, and simpler circuit architecture. The circuit enjoys electronic tunability of all the parameters in an independent but sequential manner. PSPICE simulations are included.

They are known to be highly toxic to cells, mainly through their action on cell reproduction. Many have proved to be carcinogens, mutagens or teratogens. Patients receiving therapeutic doses of these drugs have exhibited many adverse effects, including cancers. All people who came in contact with cytotoxic drug...

Periodic Research   ( P: ISSN No. 2231-0045 RNI No. UPBIL/2012/55438 VOL.-7, ISSUE-4, May-2019 E: ISSN No. 2349-9435 )  Abstract   Anita Bhawaria  M.Sc. Student, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India Kesar Chayal  Assistant Professor, Dept. of Home Science, University of Rajasthan, Jaipur, Rajasthan, India The present study was an attempt to investigate the preference of information sources by agriculture farmers. Study was conducted in Jaipur district of Rajasthan. 75 respondents were selected through random sampling method for the study and personal interview technique was used for data collection. Data related to information source used by the farmers revealed that mobile phone was the most preferred source by the farmers (70.66%). Farming helping apps (56%), television (53.33%), internet (52%) and local leader /neighbors (41.33%) always used by the farmers for accessing agriculture information. Study further revealed th...
