    change to PIC16F877A.. help.......

    how can i change this program to PIC16F877a im beginner in micro controller.. this program is use to control the speed motor.. #include <p18f4580.h> #pragma config OSC = HS #pragma config WDT = OFF #pragma config LVP = OFF unsigned char x; void read() { ADCON0bits.GO = 1; while (ADCON0bits.GO...

    check where is my error of command...

    can anybody cek my command matlab.. i want to plot X(t) signal.. ts= 0.0313 y=linspace(0,4*pi,200); x1=6*sin(3*pi*ts); figure(4); plot(y,x1,'r') hold on x2=[5*cos(6*pi*ts)]; plot(y,x2,'g') x3=[7*cos(8*pi*ts+(0.167*pi))]; plot(y,x3,'-') hold off the error is at plot(y,x1,'r').. what should i do...

    DFT X(K) frequency spectrum is not what was expected

    Re: DFT N is equal of the dicsrete signal from 0 until 6..(0<N<6) i get in what u said 4 quant level for a dynamic range ±10 would be 20/4 values. its true... if the answer wrong.. how should i get the true answer from calculating and using matlab..?

    DFT X(K) frequency spectrum is not what was expected

    Re: DFT ok.. this the question.. the question give X(n) = 6 sin (3πt)-5cos (6πt)+7cos(8πt +π/6) its want to get the quantized signal,Xq(n) with 4 quantization level using trancated technique.. and the dynamic range is ±10V.. giving N=7.. from the manual calculating i get the value is...

    DFT X(K) frequency spectrum is not what was expected

    Re: DFT hai... ihave a question.. how i can solve the signal from X(n) signal to quantization signal can give me the example of instruction in matlab how to do it.. where X(n) = 6 sin (3πt)-5cos (6πt)+7cos(8πt +π/6) N=7 with 4 level quantization using tranqated technique range= ±10V...
