Abstract: In a noise reducer for microwave amplifiers working by pulses, a small portion of the amplifier output signal is diverted through an ancillary channel. The amplitude of the pulses of this diverted signal is greatly reduced by a limiter. The noise between the pulses can then be processed in an amplifying circuit and in a phase-shifting circuit so that, by combining the main signal in a second coupler, the noise between the pulses is eliminated. This invention can be applied to transmission amplifiers forming part of a transmission/reception set where reception takes place between the transmission pulses.

Abstract: A system for the suppression of noise and its variations for the detection of a pure signal in a measured noisy discrete signal. The system measures a counting rate N.sub.2 in a signal channel and a counting rate N.sub.3 in a reference channel, evaluates the estimation value .lambda..sub.E of the ratio .lambda. between the mean noise levels in the channels and evaluates the associated false detection probability I as a function of (N.sub.2, N.sub.3 .lambda..sub.E). The system then performs a comparison of I with at least one information threshold I.sub.m, each associated with a predetermined false detection level. Comparison can take place indirectly on a function of the probability and can use tabulated values. The system has particular application to the detection of corpuscular radiation.

The memory card has semiconductor memory chips mounted on a printed circuit board. The camera operates in a motion image display mode by half depression of the shutter release, and operates in a still image mode by full depression of the release. In the motion image display mode, the driver drives the imaging device on a real time basis to sequentially derive object picture signals and supplies them to an electronic view finder to display the object in the motion image mode. In the still image mode, a shutter pulse corresponding to the shutter time external set is generated.
