"Also what would you do if the AC source had a DC bias?" What does this mean? Do we have to bias the AC source at some point?

So we can't apply AC source only?

Okay, I get that we need it to block DC while allowing the AC to pass. But if we have to block DC, why apply it in the first place? Is it because we apply it to a certain level and then we want to keep it to that level so we block any further interference by DC? Thanks.

I'm utterly confused about this concept and the textbook quite efficiently confuses me further. I'll just try to explain it with an example: The circuit has a V(cc) = 10 V and V(ee) = -10 V. V(c) = 2 V, V(e) = -1.7 V, V(b) = -1 V, I(c) = 1 mA, I(e) = 1 mA. It says that allowable signal...

I read in my analog communication book: "A relatively small increase in bandwidth buys a large advantage in terms of reduced transmission power. But a large increase in transmitted power buys a meager advantage in bandwidth reduction. Hence, in practice, the exchange between B and SNR is...

Thanks a lot! It was really helpful! Taking first course in Analogue Communication. :)

Thanks. I bit confused about this. Does this mean that the channel is best transmitted at 98.5, but it can be transmitted, with a bit low quality, in the range of 200 kHz bandwidth? Thanks.

Another related question: When we say that a certain broadband/DSL connection has a bandwidth of say, 1 Mbps, what does that mean? Thanks.

So, when we say ration station 106 (for example), we're talking about the Bandwidth. And Bandwidth means that this station/channel can be captured on all the frequencies in this band, right?

From a book: "The waveform is distorted because of different amounts of attenuation and phase shift suffered by different frequency components of the signal" Question: If there are different frequency components in a single, how do the ratio channels operate on a single frequency. A...

Here are two cases: 1- A person is a writer. He writes on issues in an aggressive manner and an arrogant tone. But in his personal life, he's quite a shy and introvert kind of guy. What does this indicate? 2- Another person is a writer. In his personal life he talks big and is rather...

Well, I do under stand *what* they do but I have trouble understanding the purpose of these transforms in simple words. Laplace transform converts an arbitrary single into exponentials while Fourier transform converts a given signal into sinusoids. As for the purpose, is the following...

Hi all! (Right now I'm an undergrad EE) I'm really having trouble deciding which field to choose in future. I want to go in the field of research and from what I know, CS has wider opportunities for research as compared to TE. Is that right? Besides, I have a deep interest for...

I do understand that logical address space/memory is generated by the CPU for the program and physical memory is the one on-to which the logical address space is mapped and which is on the physical memory. Plus, physical memory is not directly accessible to the user. Now, my question is (I...

Is there any way I can replace/embed HTTPS in place of HTTP permanently in my browser?
