how can i use an analog signal for changing resistance inside a circuit in easiest wau possible
 

Re: need little help plz

you can use a fet to do this
fets are more linear and therefore are better as a variable resistor
 

need little help plz

use junction field effect transistor as we go on changing its gate voltage its resistance in linear region changes ...
 

Re: need little help plz

use Jfet where at the gate apply negative voltage (nchanel) and by varying the voltage u can get a linear resistance in the range of 50 to50k.
