Logan’s Logo So Logan has devised a logo for her company which is a square divided into 3 sections with 2 functions. Our objective is to find what functions fit the two curves on her logo and also make it fit on two other sizes of her logo. Just looking at the shape of the lines 2 types of functions immediately jump into my head‚ sinusoidal and cubic. I first traced a grid onto the original copy of the logo I was given in order to get points to start trying to form a function to match the design

Assignment No. 1 for Communication Engineering‚ 4th sem IT students (to be submitted in class on 26/02/2013) Q. 1 A carrier signal with a peak voltage of 50V is amplitude modulated with a 1KHz test tone. The modulation voltage has an effective value of 5V. Compute the following: a. The percent modulation m b. The instantaneous voltage of positive and negative envelope when the 1KHz sine wave has completed 810 ������s of its cycle. c. Illustrate the waveform showing voltage levels and times. Q.2 Repeat

PART 2 : FOURIER SERIES Objective : 1. To show that any periodic function (or signal) can be represented as a series of sinusoidal (or complex exponentials) function. 2. To show and to study hot to approximate periodic functions using a finite number of sinusoidal function and run the simulation using MATLAB. Scope : In experiment 1‚ students need to learn using MATLAB by connect it with Fourier series‚ where students must know how the output changes as higher order terms are added

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 =

In the most simple form‚ FM digital synthesis consists of two sine waves. One is called the modulating wave and the other is called the carrier wave. The carrier wave is the only waveform that is audible. The modulating wave does just as it sounds‚ it modulates the amplitude of the carrier wave‚ and acts as a control value. The frequency of the modulating frequency controls the rate of change in the carrier wave; it controls how fast the modulation occurs in the carrier wave. And the amplitude of

Stock Market Model (Sine Curve) Sine curve is a technique used in everyday life. Whether it be from sound waves‚ to electrical curves‚ or light waves‚ sine curve is all around us. One place that is hugely affected by sine curve is the STOCK MARKET. The stock market is where “ publicly held companies are issued or traded through either exchanged or over-the-counter market”(investopedia.com). The purpose of using sine curve is to show whether or not the market is a cycle mode or a trend mode
