Frequency Analysis Quiz Q1. You have been asked to generate a single signal by summing three different sine waves of equal length (say 5 seconds). The resulting signal is sampled at a rate of 250 Hz. The frequencies of the sinusoidal components are 25 Hz, 40 Hz and 95 Hz. The amplitudes of the signals are 2.0,3.0 and 5.0 units respectively. You have been asked to plot the signal against time. Write the text for a simple m- script that can achieve this: Q2. For the signal in question 1, sketch its folded magnitude spectrum
