Abstract or Summary
  • This thesis discusses the design and evaluation of an instrument that can detect known signals in noise. This detector uses two integrators to sense a difference in the received signal between half-cycles of the known signal. The detector is useful for sensing signals in the approximate frequency range of 100 cps to 35 kcps. As an example of the sensitivity of the detector, a 100 cps sine wave can be reliably detected in random noise where the peak signal magnitude is one-fortieth of the rms noise magnitude. The detector circuit is small and is economical to build. The instrument is quite easy to operate and the results of the detection process are known within one minute once the preliminary adjustments have been made, A complete circuit diagram and a detailed set of operating instructions are given.
