Actually, my advice about using Matlab is probably the best idea for you. You can model there whatever you want and see how it interacts and it will help you understand how it all plays together.
Now you got completely lost in it :tongue2:
you can not determine frequency properties (sprectrum) from a single sample. You need more than only one lonely sample
filter with "unit pulses at z=4,5,6" is pretty hopeless. You need to have a deeper look at Signals and Systems
As for your...
Both standards deal with properties of communication channels for which they were designed.
DVB-C (C=Cable): high SNR, no multipath, channel width 10MHz
DVB-T (T=Terrestrial): low SNR, multipath, channel grid 7 or 8 MHz
Both use OFDM QAM. Maybe different CRC? The latest incarnations (-C2 and...
Filters work in the frequency domain, not the time domain. If you want to just leave out some samples, design a sequential circuit (finite state machine) that copies (passing through) all samples but the ones you don't want to.
Maybe if you shared more about what you want to achieve (we're...
I looked at the datasheet and it's pretty self-explanatory. :uhh:
No, the inputs are parallel. You have to deliver the entire 8 bits for each colour at the same time (so for red you place a 8 bit value at DIE16-23. Check the Input Pin Description section in the datasheet PDF (p.4).
No...
I think you underestimate the number of stars in universe. Supposedly there is about 10^22 -10^24 stars (see below). I don't know how many MOSFETs have people ever produced. Say a high-end CPU has a few million gates. (10^7). People have produced ~10 billion processors (10^10) so you are...
Imagine waveguides as oscilators, resonance circuits or antennas. You can force any frequency on them but only those with the correct wavelengths will resonate ("fit into the waveguide"). For the rest of frequencies the impedance will be high to the point of being infinite for some frequencies...
6*log
I bet there are values where one must calculate 5th root of a cubic of the value but people generally don't call it "6*log" but rather "10*log of ratio of 2 values each ^(3/5)".
Analysis of aperiodic signal = analysis of series of periodic segments
Sophiecentaur pretty much summed it up, I'll just say it in other words.
Audio signals theoretially are not periodic. What happens in processing of such signals is that we take a section (called a frame, a window, a...
Taking it back
Actually, it looks like I'll need to take this explanation back since it doesn't appear to be to right reason while the used AWGN is zero-mean. :uhh:
Check also this thread: White noise in communication channel
DC component means that there is energy (power) permanently leaving the source, i.e. the source is "evaporating" so it would eventually seize to exist.
Discrete time convolutions tutorials
I meant to say "discrete time functions".
I just checked Google for "discrete convolution" and "discrete time convolution" and there are some really nice tutorials and graphical explanations out there. Check out the accompanying images (discrete...
I guess I was the unlucky one. I registered today and waited for my notification mail to activate my registration for hours. At first, I thought I mis-typed my email address. I tried to verified it only to hit the "registration exceeded for this hour from your computer" page (I haven't even...
I believe you are wrong. Imagine each area as a series of thin vertical strips (same "time segment"). Each strip of the foreground function is weighted by the strip of the background function and these weighted results are then added (summed) by the integral. This way the integral is actually...
The biggest difference between combinatiorial and sequential logic is that sequential one uses memory parts (flip-flops, such as SR, JK, T, D, ...) and besides current values at its inputs can also create output(s) based partly or fully on previous values (memory parts store so-called "states"...
I just want to clarify that when I talk about "orders" I'm talking about "orders of magnitude" (i.e. the "E" in the scientific notation of a number: M x 10^E)
Brief answer: decibel is ALWAYS "10x".
Here is why (aka very long answer): decibel is one of those unfortunate units that they tell you about at the university but spend maybe
only a few minutes explaning what it really means.
The unit is actually called 'Bel' (named after Alexander...
