Hello electronic heads...

need some help here..

I need an electronic circuit to:

What is DEVICE A and DEVICE B.. you guess lar.. haha!!

Thanks in advance!!

need some help here..

I need an electronic circuit to:

what other details do you need. Let me know.1] From DEVICE A

input voltage: 4.75V to 5.25V

max input current: 0.1 mA

output voltage range: 0.50V to 4.50V.

factor P determines the output voltage, V1.

V1 (0.50V to 4.50V)2] first stage

to multiply V1 with a certainfactor, m. The output, V2 should be adjustably 50% - 150% of V1.

V2 = mV1,m = 0.5 to 1.5...................... EQ. 13] second stage

to constantly add (or substract) a certain adjustablevoltage, cto (or from) V2, irregardence of its value. For example, constantly adding 0.50V to V2.

combining EQ.1 and EQ.2,V3 = V2 + c,-0.5 < c < 0.5...................... EQ. 2

if m = 1, c = 0, V3 = V1 (not adjusted)V3 = mV1 + c ...................... EQ. 3

4] To DEVICE B

What is DEVICE A and DEVICE B.. you guess lar.. haha!!

Thanks in advance!!
