Hi my friend....
When the "call segment" instruction is executed the PCL takes the value from the label "segment" equal to 000F then PCL = 000F + 5 = 0014. Ok?
But pcl automatically is increased in a unit after executing the instruction "addwf PCL,1".
Then the true line number to execute is...
Hi... Please check te resistors values, the correct connection of the circuit, or change the 741!
The teorical gain is G=(R2/R1)+1; because is a non inverting amplifier, then G=(10K/1K)+1=11!

ic-prog pic18f4550
Hi... i dont know the values of config1 to config7!
To program the PIC18F4550 i use the WinPic800 software and JDM programmer.
Download the WinPic800:

In the attached image see the configuration values are explained...
And the config1 to config7...
Re: Attenuator?
Hi...
I dont know attenuators with diodes!
I know this attenuator from 1 db to 20 db in all frequency!
See the schematic and find the values in the next table.
The values of the resistance are given for input impedance of 50 Ohms and 75 Ohms.
Best regards from Argentina!
Re: Moto CDI sample
Hi,
What TIP transistor use? ex: tip31, 141... so on.. what?
You can give me the all values of the components, some its not listed in the schematic.
Please..

Hi,
Not is necessary understand the internal circuit of Operational Amplifier to explain the diverse configurations.
You only need to understand the principles of operation. The operation principles are four:
-Input resistance infinite Ri=∞ (no input current)
-Output resitance zero...
Hi...
Dynamic resistance of the diode is the resistance for an AC source deppending of the DC polarization of the diode.
The DC polarization determines the dynamic resitance, a high diode DC current is a minimun dynamic resitance because the variation in the curve of diode is more high then...
Re: invers fourier !!!!!
The methode is IFFT (Inverse Fast Fourier Transform) but its implementation is complicated. You can try with MathLAB by explample or Mathematica 5.0. I dont know the algorithm in C or some computer languaje.

Use a MPX motorolla sensor. MPX2100Ap its a good sensor.
"The MPX2100 and MPX2101 series device is a silicon piezoresistive pressure sensors

Re: invers fourier !!!!!
10*cos(2*pi*t*f+angle) The equation is in domain of the time.
2*pi*f : is the Angular frequency.
t: is the time
angle: is the phase
An equation in domain of the frequency is:
F(w)=(T/2)*{sen[(w-w0)*T/2]/[(w-w0)*T/2] +sen[(w+w0)*T/2]/[(w-w0)*T/2]}
Is the Fourier...
