The system relates to filed-programmable lab-on-chip microfluidic operations, fabrications, and programming based on Microelectrode Array Architecture are disclosed herein. Specifically, the present invention relates to apparatuses that increase the difficulty of well-known exercises and weight lifting techniques in order to increase the efficiency of work-outs. The selected ones of the blocks form sidewalls that surround the periphery of the electric circuit board. In another embodiment, each mismatching block is re-demodulated as soon as a global modulation technique decision is formulated and a mismatch to the preliminary modulation technique decision is detected. The small physical size of signals stubs in the univerals switches results in a signal path between any pair of terminals that may be suitable for the transmission of signal frequencies greater than approximately 500 mega-hertz.
