Hello everyone,
I wanted to know the cutoff frequency from the transfer function.
Transfer function of LPF is given by
(1-z^-6)^2/(1-z^-1)^2.
So the coefficients are
b = [1 0 0 0 0 0 -2 0 0 0 0 0 1]
a = [1 -2 1];
h = filter(b,a,[1 zeros(1,12)]);
How to find out cutoff frequency for this..?
Hi..
I wanted to connect a bluetooth to an ios android phone. Whenever any call or message received in that smartphone our device should vibrate and LED blink..
How to solve this problem..?

Hello..
I am a Beginner in Matlab.. I want to know how to give string as an input.. If I use command, input('Enter a String'); It can accept only integers.. Please suggest few websites to learn programming in MATLAB..

Hi..
Anybody helps me or give an idea "How to display float values e.g. my converted ADC value i.e, weight in terms of float on Graphic LCD"

Hi..
Gain = 0.506585(Float value)
Avalue = 00001120(unsigned long value)
Bvalue = 0000096A(unsigned long value)
Result(unsigned long value)
My equation is
Result = Gain * (Avalue - Bvalue)
How to...
Hi..
When we connect the Load cell to ADC, we cannot measure the voltage externally from Load Cell as you have told. Here I may require to convert the ADC_reading into voltage by some calculation and should perform the above calculation..

Hi Klaus,
Does the value ADCv vary for different weights..? should I measure it by putting the load on sensor or should I calculate it..?
"put no load on your sensor and read out the value (ADCv),this is your offset"
gain = 1000g / (ADCv - offset)
offset-offset will become zero.. Please...
Hi..
I am interfacing 24 bit ADC with micro controller, It is giving different increasing values to increasing load on load cell. I don't know how to convert these values into weight. Any one who has knowledge about Digital Weight Measurement, please suggest your ideas..
Crystal frequency of XMega is 16MHz. Yes, we are interfacing Load cell to ADC and one channel has to be used. So AN1, AN0 connections are taken. Purpose is to measure weight with larger resolution. Compiler is AVRISP MKII..
We are using Xmega128a1u microcontroller and 5MHz crystal for ADC. We are using only one channel. AN0 and AN1 channels are connected to circuit. Purpose is to measure the weight..
Hi...
I am trying to interface ADS1242ipwt with xmega microcontroller.. Could you please help me to solve the problem I am facing in it. I am not able to read the ADC values. Tell me how to use WREG and RREG to write and read the ADC register. Is it compulsory to use these...
