Re: Why is Phase modulation (PM) not so popular in broadcast
Phase synchronization is a very complicated task which is required in PM demodulation. This is the reason that PM is not popular.
bandwidth + linear frequency modulation
This is because the FM spectrum consists an infinite number of frequencies spaced by modulating frequency. you can see page 192 of Carlson.
There are a lot of applications for these tools. The most important application of the Autocorrelation is in obtaining the power spectrum density. Indeed the fourier transform of the autocorrelation is the power spectrum density.
cross correlation shows the correlation between two different...
There are a lot of states where resistors and capacitors are used in the electrical and electronic circuits. You should read a book about electrical circuits and one microelectronic book to learn about this issue.
Re: KVL AND KCL???
KVL states that the sum of the elements voltage in a closed loop is zero but
KCL says that for a closed surface the algebraic sum of the currents are zero.
