is it possible to measure the time period without using CRO OR DSO oscilloscopes.

Yes. What sort of time period? The interval between two pulses?

Keith.

pulse wave of 40khz, i want to measure the duty cycle of negative and positive width of the pulse
 

Well, a few options spring to mind:

FPGA/PLD - fast and accurate

Microcontroller e.g. PIC - easy to do but limited accuracy

Analogue method with analogue output - possible but tricky to get accurate.

Out of those, I would look at the microcontroller method unless you need very high resolution. I am not sure of the PIC timer/capture resolution, but I think a 20MHz should be around 200ns, but I may be wrong.
