Help me in calculating voltage drop

[maestrominion]

hello,
I need to calculate voltage drop across resistors highlighted in the attached embedded circuit.I'm not technically high.Can someone help me.Thanks in advance

Hi maestrominion, and welcome.
Unfortunately, your drawing is in .PNG format and it impossible to read the component types and values - even with a screen magnifier. It would be helpful if you could show just the left hand side of the circuit, in .GIF format.

To work out your problem it is necessary to know the zener types and voltages, and the waveforms type and voltages at two 'X' inputs. It would also be helpful to know the type of IC used.

please elaborate the values of all components.

Use OHMS Law. To calculate the voltage drop you must know how much current flows through the resistor.
Your diagram does not give any information regarding the resistance (R) nor the current (i). So unfortunatekly no one can help you except as I did by telling you to use OHMS Law.
OHMS Law is the very first thing to learn when starting in the field of electronics.
Okay the supply voltage is 5v so I am sure you can now take it from there but there is already a "dropping" resistor before the one you are interested in.
