AM/FM modulation & Demodulation

[beramodo]

Hello now I'm studying about AM/FM modulation & Demodulation

I wanna modulation sound whatever voice or soundfile to modulated signal

and demodulation form that to excutable sound signal like original sound

in the follow screenshot is simple am modulation

this block diagram mean as you know : (Carrier * signal)+carrier  = DSB-tc

problem is "Simulate Signal.vi" harm original signal to nomal sine signal

so i connected directly from input to multifly but that make error "Waveforms have different dt values"

at this point of time I wondering how could i multifly or add original signal with carrier

that was main problem

in addition If you can reply about how cound demodulate from modulated sinal to sound

and How could I play sound without delay in 'Acquire Sound.vi' I will be really appreciate 

Thank you in advance for your help
