i don't software to draw this circut can u give me one

who can i do that

i want to send patient tempareture so at first i have sensor (AD22100) with 10 degree range after that send the voltage of the sensor to VCO to convert v/f (TS902). but between the sensor and VCO i need op amp (741) but when i connect it the offset apper in the result and i am connect...

ok thanks but can u give me any example with value of input and resistor and what the solution

please can anyone give me clearly information about Op Amp Offset Voltage with simple example and rule to explain that becaus i was found diffecalt to understsnd it .

thank u very much for your time but i want any web show me who can i work ?

yes but i need more information about the sensor , vco , fm modulation ... ect , that used in this case

i want how the wireless temperature monitor allowing the status of the patients in different hospital room to be remotely monitored by doctors and nurses. A micro processor is used to watch the patient temperature continously from a remote place. Once the patient temperature exceeds its...
