problem with transistor based FM transmtter is that output freq. is not fixed . so if u use digital FM receiver such like in ur mobile phone u will be unable to receive signal. so u have to use manual analog radio receiver to receive ur signal. I think a lots of transmitter ckt available on web...
i am performing my project on sigma delta ADC . which topology should i use , single bit / cascade. and also if u have some idea about digital decimation filter used in Sigma delta adc pls post it:lol::lol::twisted:
Re: need help in project
u can connect humidity sensor with ur project. i 8051 code use can insert a temp comparing system i.e if current temp is higher than thresold then there will be some alarm or another system that decrease current temp of system.but 8051 is not suitable for these type...
thats ok, i am telling u what is my prob. and what i am doing:
currently i am using tanner tool v13. often i use s-edit and tspice for simulation purpose and mainly i work on analog circuits i,e CMOS amplifier , opamp etc.
Currently i am designing a cmos opamp for my project. design & T-spice...
I am using tanner tool 13.i want to generate layout and padframe of a schematic so i export it as tpr file, but how i find suitable library file for standard cell place & route(spr) setup ? i use some example library file that is in tanner library but they give some error such like 'rowcrosser...
first check whether the data are successfully sent to PC from micro controller. U can use Hyperterminal available in start---> program-->accessory-->communication-->hyperterminal in winXP. first set parameters as port-- com1 or com2 according to ur PC, baud rate(same as sender) ---> parity none...
Re: sinc 3 sigma delta
:oops:u can try Matlab Filter Design Toolbox Available in Matlab 7.7 version
there in command window execute 'filterbuilder'
.............. follow steps and u can generate any type of filter with it's HDL code
