    could you please help me analyze the circuit i uploaded .it is based on REMOTE-CONTROLLED POWER-OFF SWITCH

    please tell me y we are using the specified resistance and capacitance value

    For the most part the values were chosen because they seem to work. I doubt the long term reliability of this circuit given IC3 is shorting out C5 and is thus overstressed.

    The author gives a decent enough description, you should start there, then come back with any specific questions you have. No one is going to work this out for you as it would take hours for any kind of detailed analysis.

    Will the circuit work without the timer and counter circuit?

    No. Why in the world would the designer put them there if they had no function?

    If you're asking if you could create a simpler IR-triggered remote switch without those parts, then yes. But it won't have the same features as that design.
