ABSTRACT:
A signal whose RMS value is to be accurately determined is first converted into DC form by a relatively inaccurate RMS converter, such as a thermal RMS converter (15). The result is a first converter signal (Y.sub.1), which is stored for recirculation in a suitable device, such as a sample and hold circuit (17). The first converter signal is also doubled (2Y.sub.1) and stored (41). Thereafter the first converter signal stored in the storage device is recirculated to the converter to create a second converter signal (Y.sub.2). Then, the second converter signal is subtracted (43) from the doubled first converter (2Y.sub.1 -Y.sub.2) to produce a highly accurate RMS output signal.
