    I find this blocks diagram for heart pulse meter
    But there isn't explanation about this blocks diagram
    I will glad if anybody here can help me to understand this or part of this blocks diagram
    or can write me where to search information about this electronic parts


    also I search after small RF module for short range (1.5 meter) like the RF module that appear in heart pulse meter in polar hand clock or in bicycle velocity meter
    this RF module can transmit digital information
    this is important to me that this RF module will be in small size ​

    The block diagram you posted is nonsense once you get to the 1st HPF.
