Hi every one,,,
I used to navigate this forum once in a while to explore the ideas of the members, but now I am facing a problem in an electronic circuit I designed.
Well I want to store a sound file in an EPROM M5L2764 which can hold up to 8k bytes of data and then play the sound file using DAC0808 with a LPF and an opamp.
I used 14 bit counter connected as the address of the EPROM
and the data coming out of the EPROM is exactly the one shown in the HEX representation of the file using HEX Probe editor.
Further more the DAC0808 workes perfectly except that all what I hear is noise even though I varied the frequency of the counter from 1 kHz to 1MHz.
Does anybody know what is the problem? I personally suspect that the data from the file is not the actual representation of the sound!
