(c) fundamental and harmonic sine waves whose amplitude decreases with
the harmonic number
(d) sinusoidal voltages, some of which are small enough to ignore in
practice

4.Indicate the false statement. The square of the thermal noise voltage
generated by a resistor is proportional to
(a) its temperature
(b) Its resistance
(c) Boltzmann’s Constant
(d) the bandwidth over which it is measured

5.If the plate supply voltage for a plate modulated class C amplifier is V, the
maximum plate-cathode voltage could be almost as high as
(a)4v
