Under the auspices of [1] Pimpri Chinchwad Education Trust (PCET), the [2] Pimpri Chinchwad College of Engineering & Research (PCCOE&R), Ravet, was founded in 2014. . Presently, the Institute offers undergraduate programs in five disciplines: Civil engineering, Computer Engineering, Electronics and Telecommunication, Information Technology and Mechanical Eng

As an example, a telescope having an f /6 objective and imaging at 0.55 micrometers has a spatial cutoff frequency of 303 cycles/millimeter. High-resolution black-and-white film is capable of resolving details on the film as small as 3 micrometers or smaller, thus its cutoff frequency is about 150 cycles/millimeter.
The cutoff frequency of the TM 01 mode (next higher from dominant mode TE 11) in a waveguide of circular cross-section (the transverse-magnetic mode with no angular dependence and lowest radial dependence) is given by = =, where is the radius of the waveguide, and is the first root of (), the Bessel function of the first kind of order 1. The ...
f L is the lower cutoff frequency (-3 dB point) of the analysed system, measured in hertz. f H is higher cutoff frequency (-3 dB point) of the analysed system, measured in hertz. h(t) is the impulse response of the analysed system in the time domain. H(ω) is the frequency response of the analysed system in the frequency domain.
The cut-off frequency can be determined from the cut-off wavelength. From the sampling theorem, we know that for wavelengths smaller than 2 a {\displaystyle 2a} , or twice the sampling distance, every mode is a repeat of a mode with wavelength larger than 2 a {\displaystyle 2a} , so the cut-off wavelength should be at λ D = 2 a {\displaystyle ...
In idealized ray optics, where rays are assumed to converge to a point when perfectly focused, the shape of a defocus blur spot from a lens with a circular aperture is a hard-edged circle of light. A more general blur spot has soft edges due to diffraction and aberrations, [5] [6] and may be non-circular due to the aperture shape. Therefore ...
C suffers from the disadvantage that it does not reach a maximum of 1.0, notably the highest it can reach in a 2 × 2 table is 0.707 . It can reach values closer to 1.0 in contingency tables with more categories; for example, it can reach a maximum of 0.870 in a 4 × 4 table.
