Hi, I'm new here and hoped to find some help to increase my understanding.
I came across a question asking for modulated and demodulated signals whereby the given signal is x(t) = cos(2pi10t),
and the carrier signal is c(t) = cos(2pi100t).
I know that to get the modulated signal I need to multiply m(t) = x(t) * c(t) to get maybe frequencies of 90Hz and 110Hz.
To get demodulated signal I need to multiply d(t) = m(t) * c(t).
I don't understand the way of multiplication this part and maybe anyone can help?
Also, how can we recover the original signal from that d(t) and how do I go about setting the parameters?
Sorry but this kind of questions may seems noob to most you guys, but I'm just started learning these signal processing thingy and got quite a headache in the calculation part. Hope you guys could help =)
