Hello
I need to tune the channels using 89c52. The tuner needs 0 to 33 volts, and steps should be very fine (in some milivolts) I believe.
Have tried 16 bit ADC but results are poor. All the channels cant' be tuned.
Can anyone help:?:
I checked up in the TV, which uses Phillips TV processor. That processor used some intelligent algorithm and generates complicated PWM. Works marvellous.
I tried to write the software to generate the waveform. But the execution time required is high even after running the 89C51 at 40MHz.
Thanks
