A new bit-to-bit ratemeter based on rate multiplication is described. The ratemeter is part of a signal monitoring and processing system used to analyse, respiratory signals of neonates that are characterised by low and unstable rates. The advantages of the new ratemeter are discussed and a comparison is made with other meters. The response of the ratemeters is demonstrated by means of simulated signals as well as actual neonatal respiratory signals.
