Cancelling periodic noise signals at the input to sensing systems significantly eases the requirements for dynamic range, loop gain and slew rate. A method of cancelling mains-induced noise at the input to a SQUID magnetometer has been demonstrated t

A digital synchronous filter for rejecting periodic noise such as that arising from the mains power supply is described. With a stationary noise signal the filter achieves a rejection ratio of 127 dB. With the somewhat variable mains, rejection ratio

Measurement of the effects of passing alternating currents in the frequency range 10-105 Hz through a group of saturated standard cells showed that their internal resistances declined with increasing frequency at a mean rate of 25 Ω/decade. AC cause

The results of a high accuracy numerical study of the uniformity of the electric field between parallel disc electrodes are reported. Simple analytical expressions are derived describing the field behaviour at points on the electrodes near the edges

The volt has been determined to high accuracy using a liquid electrometer. The representation of the volt maintained by the Josephson effect using the value of 2 e/h = 483.594 THz/V recommended by the Consultative Committee on Electricity of the Inte

It is shown that a parallel-plate capacitor with a sinusoidal defect in one of its electrodes has the same capacitance as a plane electrode capacitor with slightly smaller inter-electrode spacing, and the same force per unit area as a plane electrode

Short latency somatosensory evoked potentials recorded with median nerve stimulation at the wrist have been widely used to assess pathology affecting the sensory pathways. The generator sites for some response components have been well established (P

Recent determinations of the volt and the quantized Hall resistance at the Australian National Measurement Laboratory have yielded values having sub-ppm uncertainties for a number of important fundamental constants. The direct experimental results ar

A proposed method for the precise realization of an absolute standard of dc voltage requires, inter alia, the measurement of a number of spacings, of order 2 to 5 mm, between a horizontal reflecting mercury surface and an upper semitransparent film.
