DSB Modulation for an Almost Bandlimited Signal] The message signal m ( t) is given by
![]()
where to = 0.1. This message modulates the carrier c(t
 ![]()
1. Determine the modulated signal u ( t)
2. Determine the spectra of m(t) and u(t).
3. If the message signal is periodic with period To = 0.2 s, determine the power in the modulated signal.
4. If a Gaussian noise is added to the modulated signal such that the resulting SNR is 10 dB, find the noise power.
