Laboratory 3: Diode Characteristics Instructions: Unless otherwise mentioned in the experiment instructions‚ all experiments are performed both in SPICE and physical implementation. The results need to be reported from both the SPICE and physical measurements. 1 Current voltage characteristics of diodes 1. Design a circuit to measure the forward-bias current voltage characteristics of diode as shown in Fig 3 using Circuitlab. Figure 1: A SPICE circuit for plotting current voltage

Tutorial Sheet # 2 1. Sketch the time variation and frequency spectrum of an RF signal with 75 % Amplitude Modulation. Show several cycles of the modulated wave. Make the modulation frequency 1/10 of the carrier frequency. The unmodulated carrier has peak amplitude of 1.0V. In an amplitude modulation system‚ the message signal is given by Fig. and the carrier frequency is 1 KHz. The modulator output is SAM (t) = 2(b + 0.5m (t)) cos ωc t. 2. a. Determine the average message power. b. If b =

result is tragedy. Needlessly‚ thousands of lives have been lost due to simple human mistakes in the very place where the best chance of saving those lives could be found. Despite the expense and hurdles of implementation‚ the establishment of an Electronic Medical Record (EMR) infrastructure is an essential key to saving lives and money over the long term. Admittedly‚ putting an interconnected network of EMR systems throughout a country is a daunting prospect and will be time-consuming and expensive

In one episode of the TV series The Big Bang Theory‚ someone ruins the movie Raiders of the Lost Ark by pointing out that the character of Dr. Indiana Jones is irrelevant to the actual story. In a similar vein‚ some historians make the argument that Abraham Lincoln is not critical to the Civil War and its outcome: the war happens anyway‚ even if Lincoln had never been born‚ and the North still would have won if someone other than Lincoln becomes president in 1860. That is considered to be double
