- Except where noted, all signals, carrier, and modulated signal
have dimensions of volts (V). Frequencies are in units of hertz
(Hz) and time in seconds (s).
- When requested to present T.F., S.F., DEP or DEE, clearly
explain the frequencies, amplitudes and
phases of the spectra involved, with units on the axes.
SSB signals can be generated with and without carrier
highlighted. be then

with mH(t) being the Hilbert Transform of the message m(t). The
parameters Ac and fc are, respectively, the carrier amplitude and
frequency.
(a) Justify if the sign sssb+c (t) may or may not be demodulated
using a PLL-type circuit. If so, provide a block diagram of the
receiver. If not, provide the reasons for the impossibility;
(b) [FR1] Express sssb+c (t) in the form,
