i know that for a given signal, there exists a corresponding freq spectrum. but i'm am baffled by my thought. can somebody explain this:
imagine this time domain signal: 10*sin(wt)u(-t)+5sin(wt)u(t)..i.e.sinusoidal signal is at one amplitude for -inf to 0 and another amp for 0 to +inf...
Not a stupid answer :
A regulator that you often hear about is Voltage regulator.There are other types also.
Now a voltage regulator regulates the voltage - it keeps the voltage at a constant level regardless of fluctuations at input.
Most frequently used regulator - LM7805. It keeps the...
Unable to run Matlab 7
i'm unable to use matlab 7 on Windows XP SP2 now. when i run the matlab program the flash screen appears and disappears but nothing happens(no
workspace). it was working when i last used it a couple of months ago.even the m file editor and un-install programs do...
i'm unable to get the concept of "phase". i come across this word in several contexts like phase response, cos(wt + phase), e(jwt). ......
Can somebody explain what phase is mathematically and physically. and how to accept it by intution . or reference to any website would be also helpful.
Incidentally this happened to be my first circuit with avr. I too used 7805 and a hexfet for driving a motor. It worked. You should first check your algorithm. If thats not the problem try using 2 capacitors one at iput an dother at oput of 7805
I'm not sure about how much programmers cost... but for 50 bucks you could make yourself one. It is a very simple circuit. Google 'pony programmer'. check the first link you get. there are two schematics given in the website. go for the simple one.
Let make it simple by taking an analogy. What is slap response ? The way you respond when somebody slaps you. What is impulse response then ? The way a system responds at the output when an impulse(think of it as an electrical 'surge' for time being) is applied at the input.
Is it applicable...
what is pseudo bipolar input
Whats the difference between pseudo bipolar input and truely bipolar input ADC ? I haven't found a site or a book that explains the term pseudo bipolar. Any link or book or suggestion is welcome.
Re: AVR registers
even i've tried looking for this answer. but haven't found a logical one yet. most websites bring this point and end it there.
but i guess AVR designers tried to sqeeze in more instructions that occupy 1 word
its not easy to learn by going after free hardware. you can learn atmel avr. it is easy to learn and program aswell. and you can get started with minimal cost compared to other uc. try www.avrfreaks.net for more
i'm using parallel port for simple interfacing. i am able to output data to parallel port. But i'm unable to receive data from the port. I tried making C5 = 1(loaded 20h into 37Ah), but when i read back from the port, i got C5=0 (0C0h back). Unable to change C5 bit.
How can i...
I'm relatively new to assembly. I want to create graphics using the
video memory(B8000) directly for displaying the data received from DAC . i've been able to create graphics using a blank character with a coloured background in 80x25 mode.
1) Whats the memory scheme if I increase the...
