[@pegasusdiaries-journeyofab2378]

Is is Fourier series or ft??? Gp(t) not clear at all

[@motjones2341]

It is not clear because he does not understand the physical reason the sidebands are generated, so like all professor just rely on some math to explain the result, but not understanding the how and why it happens. sorry, all professor do not understand this on all Indian videos and all others on internet too.

[@prapti.borthakur]

Sir can we write gp(t) directly without showing the Fourier transform steps?

[@justadreamerforgood69]

It's Fourier series not Fourier transform

[@AsfiaMirza]

Why do we always pass through BPF and not any other filter? Even in case of Square Law Modulator, BPF is used.

[@janithavidunath]

Because we have to avoid law frequency components which are use less. If we use law pass filter then there will be a DC component

[@saiprakashputrevu7512]

How the odd harmonics in gp(t) all get eleminated without passing through any filter...

Oho Yeh BPF se pas krne ke bad hi eliminate honge bola to sir NE

[@justadreamerforgood69]

Do the Fourier series of the wave and you'll see the odd harmonics are eliminated. It's related to something of half wave symmetry or quarter wave symmetry. I can't remember rn but if I solve it I'll remember

[@bhootbangla5404]

Can anyone pls explain me how gp(t) came in this output signal representation..?

[@pranavc4397]

Hello Goku ;P gp(t) is a way of representing the output signal. It doesn't exist in the circuit. We know that due to diode negative peaks of the input signal are vanished at the output section. If the time period of input signal is T, then on period of positive peak will be T/2 i.e time period of positive peak. So output will have postive peaks at every T/2 spacing. To be more clear just draw the sine signal and shade the positive peaks and erase negative peaks then you can clearly see positive peaks of period T/2. This is the output signal, now to represent the entire signal it requires complex math terms. To make it simple we can view the output signal as on period multiplied by original signal. This on period is gp(t), and that's the reason it has the width of T/2

[@venkateshmandavilli2074]

Sir how are you saying that the diode will on without mentioning voltages at anode and cathode ?

[@mayanknarang6788]

Anode pe to c(t) + m(t) hoga but cathode pe Kya hoga vo Carrier ke nature pe depend krega

[@husainmurabbi1606]

can anyone tell me how does modulation index comes out to be 4/pi*Ac?

[@shivaa9901]

It is amplitude sensitivity.

[@tharanianand6183]

Sir its not audiable... please take in high volume.

[@vikingak4799]

Sir can you help me with this? Design and implement a switching modulator in MATLAB for Modulating a composite audio tone signal to the medium wave (MW) AM band which is used for radio broadcasting. The information signal is supposed to be a dual tone having two sinusoids X+1 kHz and Y+2 kHz, where X and Y are the first and second digit of your Roll no. respectively use the other best suited parameters of your choice for the camer frequency, filter types and their bandwidth. Analyze the time signals and their spectra at different stages of the implementation.
