 		 #168456 - Few Questions
Responding to: ???'s previous message
Dear Ghulam,

Ghulam Mustafa said:
hello,
i am working on sending a continous analog signal like sine wave of 4 hz through the serial communication using 8 bit ADC and 8051. But facing two problems.
1- Quantization error.
2- the limitation of speed (while i used the communication at 19200)
So i am sticked at using a new controller which i think must send a 16 bit data.
So i want a suggestion from you that which controller should i use?
Wel i am already fimiliar with 8052 series so i would like to work with a controller for which i doesnt require many new tolls.
Thanks


First of all which controller are you using now?
Does it has ADC / DAC on chip? or you are using external chip?

Also what are the properties of converter (Conversion Time, Resolution etc...)that shall solve your 2 problems to some extent,

Regards,
Mahesh

                     Can you provide more detial            01/01/70 00:00      
                        Always focus on signal integrity            01/01/70 00:00      
                  not so fast ...            01/01/70 00:00      
                     Pls also identify there solutions            01/01/70 00:00

                              Get rid of them, probably not, but ...            01/01/70 00:00
