if you are that sure show me the way, i too can go with the way you mentioned but finally my filter to work i have to fill my filter coefficients with the needed
but not what i obtained :)
tell me if u have a way
Hello Audio Experts and aspirants,
First of all i will try to put my agenda of my system:
>capture of ubiquitous speech of a area under surveillance and further transfer it to a RF module that's it
In that event i have chosen to use a stereo codec chip from TI - AIC3204 which has inbuilt...
https://www.itu.int/rec/T-REC-P.863-201101-I/en
i have downloaded from the link provided in the p.863 but i could not able to check the speech codecs MOS as like the p.862 in which in source folder if try to compile all files we will get a executable and we can use it for evaluation but now in...
Actually i am working on a simulation which mimics the subjective analysis of MOS(Mean Opinion Score) Evaluation
My job is to compare the low bit rate codecs with ITU-T standard P.862
So i downloaded the software from the site

YES I HAVE DONE THAT
its working then but when i try to connect it with the rf tx and rx the problem arises
the datain keeps changing and dataout reads only 0.4v each what ever the switch preseed at the tx
iam getting teased by my RF TX AND RX
ok let me explain your very eloborately see these pictures these are my rf tx and rx ciruit on which i have been working
my problem is " iam not able to understand what my problem is "
when i try to transmit data from my tx im not...
how to identify tip and ring
but the jack has two wires each with another pair some thig like show in figure
one with red and a copeer coloured wire
and other with green and copper couloured
now how to connect these things to the circuit i have
actually i quited from this project bcoz the hm2007 is very costly piece in my country
i hav attaced the pdf above that all i have it has some programming and assembling tips of connecting hm2007
good luck
Re: is it 8870 or the jack teasing me help me plzzzz
sorry i havnt got your point do you want me to change the resistor next to capacitor by greater than 100k ,i think that would certainly stop the dtmf
or the resistor to pin3
plz suggest me in detail
hai here i have a peculiar problem
i have taken the dtmf output form mobile(nokia 2626)
what will be the voltage of the dtmf signal???
i hav kept a voltmeter at the mobile jack to measure the output voltage from jack
it reads zero?????
ok leave that ihav two wires from the head set one is a...
