Sketch two periods of a cosine wave, y(x,t) travelling in the x-direction Make sure that your axes are labelled. Let y(x=0,t) = +A.Annotate the sketch with: the amplitudes, +A and –A; the wavelength λ; the direction of travel (labeled with velocity, ‘v’); ‘crest’; ‘trough’. Point with arrows and label the points along the graph that are: i) in phase with y(x=0,t) and, ii) 180 degrees out of phase with y(x=0,t)

(A.) Use MATLAB to generate a pulsed sine wave signal having a frequency F-10KHZ and a pulse width of T-.5ms. The pulse repetition time is 1ms (pulse repetition rate is 1000 pulses/sec), i.e., the signal is zero between pulses. Model the signal to start at time t-0 and to end at a time t=Tstop. Use a sample time of .001ms to approximate an analog environment. Display the signal in MATLAB appropriate for an analog signal, first for Tstop 1ms and...
