Performance Task for Lab Report: (your ID =
19-40083-1)
**Generate a composite signal using three simple signals
as,
x1 = a1*cos(2*pi*f1*t), x2 = a2*sin(2*pi*f2*t), x3 =
a3*cos(2*pi*f3*t)
signal_x = x1 + x2 + x3
Select the values of the amplitude and frequency as follows: a1 = 1
+ 4 + 1, a2 = 1 + 0 + 2, a3 = 1
+ 0 + 1, f1 = 1 + 0 + 1, f2 = 1 + 0 + 2, f3 = 1 + 4 +
1.
(a) Show time domain and frequency domain representations of
signal_x in a single figure
window using subplot. Use axis, or xlim, or ylim to appropriately
represent the signal.
(b) Quantize signal_x in 8 equally distributed levels and provide
image for one cycle of the
original signal and quantized signal. Use axis, or xlim, or ylim to
appropriately represent the
signal.
