Re: nyquist freq.
you if i have an analog input of 1MHz and is to be sampled 32 times ii don't need a ADC that have a capable of a sampling rate of 32MSPS?
in a input frequency of 1Mhz
*nyquist tell that the fmax must be at least x2 the fs
and if i have fs of 1Mhz and must be have a 32 samples that this affect the fmax needed?
i have a problem with the (0V - 220V)analog input of the DSO.. i need to minimized/attenuate it to 0V - 5V... what viriable gain amplifier or programmable gain amplifier would you recommend
Re: a/d converters
thnks men........
now we have a 0 to 220v peak-to-peak for the oscilloscope..... can you give me some advise and schematic for attenuator ckt. to reduce the input-siganl by 100
Re: a/d converters
ohh ye i forgot...........
i will restate my question..........
what ADC is to use....... amplitude the volt/division in the oscilloscope, right....
if the selction of the vertical axis sensitivity is from 1mV/div to 5 V in 12 ranges (real-time)
Re: a/d converters
i think you didn't uderstand the question......
i need to know the right ADC to use for a Digital storage oscilloscope that have a output amplitude of 1mv to 35v rating
