Optimum performance is achieved in fully portable system by utilizing combination of 747 opamps for A1 and A2 with National LH002CH opamp for B1-B3 and special AD521K instrumentation amplifier for output stage. Bypass capacitors suppress undesirable high-frequency signals. Stevens-Arnold DC/DC converter operating from 12-V storage battery provides required regulated ±15 VDC for system while giving excellent power isolation.-D.
