Figure A below depicts the communication system that you have simulated during the laboratory session. Questions in this section relates to the session.

1If the base band signal (in mV) is described by the following expression v = 3 sin (2π * 30t), determine its frequency. If the baseband signal (in mV) is described by the following expression v = 4 sin (2π * 200t), determine its amplitude. 3If the carrier signal (in mV) is described by the following expression v = 40 sin (2π * 1*10³t), determine its frequency. If the carrier signal (in mV) is described by the following expression v = 20 sin (2π * 2*10°t), determine its frequency. If the baseband signal (in mV) is given by v = 1 sin (2π * 3t), and the carrier signal (in mV) is given by v = 5 sin (2π * 60t), determine the highest and lowest voltage readings that can be observed on the scope.
