The frequency and the sine wave was set by the function generator. The input, output wave forms were observed from the CRO. The conditions taken were a 50KΩ , 1KΩ and a current source. The input was fed to the 2.1...
Read out allWe wanted to use the transistor as an amplifier. The input voltage at the base was 3v. Two resistors, one at the emiiter(R1) and the other at the collector(aR1) were connected. 9v supply was given at R1. Constraints : We wanted head...
Read out allWe wanted to use a transistor as a current source. Two resistors, one at the emiiter(R1) and the other at the collector(R2) were connected. A voltage divider circuit with a supply of 9v was connected at the base that could supply certain...
Read out allFirst started with constructing constant current source using PNP transistor with 9V supply voltage. CONSTANT CURRENT SOURCE: voltage reading: 3.32V ...

Read out allSAMPLING: A continuous time signal can be represented in its samples and can be recovered back when sampling frequency fs is greater than or equal to the twice the highest frequency (fm) component of message signal. i. e fs ≥ 2fm. Consider a...
Read out allMany teachers struggle with teaching division to children and I have been thinking about this recently. I think there are a number of factors contributing to this. Firstly, there is a huge range of level of understanding of the concept of division...
Read out allFor the first few weeks I decided to teach and learn with the 5th graders at Isai Ambalam middle school, at class we worked out many logic puzzles. The class was at the stage of working out multiplication and division. Speed,distance,time and...
Read out allScratch stories with Udavi 8th graders The 8th graders at Udavi had made stories on the theme ‘ if i had wings ‘ , they were wanting to depict their stories with scratch. The time offered was four English class hours on...
