Hello everyone, here the given question is a sinusoidal carrier voltage of 80 volts amplitude and 1 mega h frequency is amplitude modulated by sinusoidal voltage of frequency 5 kilo h.
00:13
Producing 50 % modulation, calculate the amplitude and frequency of the lower and upper sidebands.
00:19
So here amplitude of both, amplitude of both lowered sideband and upper sideband.
00:33
Equal which is given by mec by 2 so we have the mass 0 .5 m value and 80 divided by 2 that is 20 volts okay now frequency of lsb frequency of lsb equals to fc minus f s that is equals to thousand minus 5 kilo h h that is equals to 995 kilo hedge.
01:14
So frequency of usb, frequency of lsp, is equals to f .c minus fs, that is 1 ,000 minus 5, that is equals to 95 kilo hedge.
01:31
And frequency of usb, frequency of usb equals to fc plus s, that is 1 ,000 plus 5...
