A sinusoidal voltage trace displayed by an oscilloscope is shown in
Figure 10.19. If the 'time/cm' switch is on 500µs/cm and the 'volts/cm'
switch is on 5V/cm, find, for the waveform, the frequency, the peak-
to-peak voltage, the amplitude, the r.m.s. value.
The equation of an angle-modulated voltage is v = 10 sin (l08t + 3 sin 104,). What form of angle modulation is this? Calculate the carrier and modulating frequencies, the modulation index and deviation, and the power dissipated in a 100-ohm resistor.
