Gamma, Return Loss, and VSWR w7zoi, 18July06 We are always interested in the performance of the circuits we build. If we build an amplifier ora mixer, we are primarily interested in the gain of the circuit.
92 A TECHNICAL INTRODUCTION TO DIGITAL VIDEO a power function of intensity. This characteristic needs to be considered if an image is to be coded so as to minimize the visibility of noise and make effective perceptual use of a limited number of bits per pixel.
SECTION 3 - PROPERTIES OF ALPHA. BETA. GAMMA. X RAYS AND NEUTRONS There are four main types of radiation (we include y and x rays as one type) which must be dealt with in health physics.

Gamma Ray Spectroscopy Physics 149 The aim of spectroscopy is to measure the energy and number of photons. To do this, we must somehow arrange to detect the presence of photons in a way that differentiates one photon from another based on the photon's energy.
