Highfrequency是什么意思
Web28 de mai. de 2024 · We investigate the relationship between the frequency spectrum of image data and the generalization behavior of convolutional neural networks (CNN). We first notice CNN's ability in capturing the high-frequency components of images. These high-frequency components are almost imperceptible to a human. Thus the observation leads … High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters). Frequencies … Ver mais The dominant means of long-distance communication in this band is skywave ("skip") propagation, in which radio waves directed at an angle into the sky refract back to Earth from layers of ionized atoms in the Ver mais The most common antennas in this band are wire antennas such as wire dipoles or rhombic antennas; in the upper frequencies, multielement dipole antennas such as the Yagi, quad, and log-periodic antennas.
