I would like to know how to convert the analogue signal to digital signal and digitize to display the value in computer?

Which data logging i have to use? Does Arduino board can be use?

Which of the type of magnetic pickup sensor can be use? The minimum requirement and low cost of magnetic pickup sensor.

Sounds like a homework assignment to me.

What kind of magnetic pickup sensor is it? If you use a Hall Effect sensor, the signal is a square wave which is essentially digital. Any data logger with a scaleable pulse input can see it, although you may need a pull-up resistor.

Good luck with your class.

Assuming a sinusoidal output from a reluctance device, start looking at comparators/op-amps and hysteresis, set points on rising/falling wave switch on off producing square wave output.
