Direct drivers of deforestation in Amazon countries Cattle ranching Cattle ranching is the leading cause of deforestation in the Amazon rainforest. In Brazil, this has been the case since at least the 1970s: government figures attributed 38 percent of deforestation from 1966-1975 to large-scale cattle ranching.
The sampling frequency or sampling rate, fs, is the average number of samples obtained in one second (samples per second), thus fs = 1/T. Reconstructing a continuous function from samples is done by interpolation algorithms.
60 X 245 X 3 = 44.1 KHz. In 50 Hz video, there are 37 lines of blanking, leaving 588 active lines per frame, or 294 per field, so the same sampling rate is given by. 50 X 294 X3 = 44.1 Khz. The sampling rate of 44.1 KHz came to be that of the Compact Disc.Even though CD has no video circuitry, the equipment used to make CD masters is video based and determines the sampling rate.0 X 245 X 3 = 44.1 KHz. In 50 Hz video, there are 37 lines of blanking, leaving 588 active lines per frame, or 294 per field, so the same sampling rate is given by. 50 X 294 X3 = 44.1 Khz.
