Pemantauan Flicker Tengangan Menggunakan Fast fourier transform (FFT)
Voteteknika (Vocational Teknik Elektronika dan Informatika), 2021 Laju elektrifikasi Sumatera Barat 92,96%. Jumlah ini akan terus meningkat setiap tahun, dan dengan meningkatnya laju elektrifikasi di Sumatera Barat maka kualitas daya yang dibutuhkan akan meningkat. Di sisi lain, peningkatan kecepatan pengisian menyebabkan penurunan kualitas daya. Kualitas daya sistem tenaga dipengaruhi oleh gangguan. Dengan kata lain,

Numerical evaluation of the Hilbert transform by the Fast Fourier Transform (FFT) technique [PDF]
Geophysical Journal International, 1981 Summary. Three Fast Fourier Transform numerical methods for computing the Hilbert transform have been evaluated for their accuracy by numerical examples. All three methods employ the property that the Hdbert transform is a convolution. The first method uses the result that the Fourier transform of 1/πx is — isgn(ω).

An extensible complex fast Fourier transform processor chip for real-time spectrum analysis and measurement [PDF]
, 1998 This paper describes in detail the design of a CMOS custom fast Fourier transform (FFT) processor for computing a 256-point complex FFT. The FFT is well-suited for real-time spectrum analysis in instrumentation and measurement applications.

IMPLEMENTATION OF FAST FOURIER TRANSFORM (FFT) FOR INFANT CRYING DETECTION
Indonesian Applied Physics Letters, 2023 Babies cry based on the discomfort felt by the baby which is a reflex such as when a hungry baby will suck his hand and then he will start crying, hunger can be interpreted from the baby's crying. At each of the baby's cries, when each crying pattern was responded to with the solution applied to the previous baby, each baby would stop crying.

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.
