The signal m(t), whose frequency spectrum M(f ) is to be transmitted from one station to another. Let the signal be nor- malized, i.e., -1 ≤ m(t) ≤ 1. Find the bandwidth of the modulated signal:
(a) If USSB (upper single sideband) is employed.
(b) If DSB (double sideband) is employed.
(c) If an AM modulation scheme with a modulation index of 0.8 is used.
(d) If an FM signal with the frequency deviation constant k = 60 kHz is used.
D Flip Flop As we have seen in the SR flip flop when the inputs S= R are applied the forbidden or indeterminate state occurs. This state can destabilize the SR file flop.
