2021/6/23High frequency trading (HFT) is one of the most mystical and often misunderstood elements of capital markets. Brought to popular culture with Michael Lewis' book "Flash Boys," HFT is synonymous with speed, technological innovation and secrecy. HFT quant
2018/3/26High freguency isn't a well defined term. Most of us surely think that HF transformers are complex to design, analyze and make, because several non-idealities grow substantially as the frequency increases. For example many iron cores, which are excellent for 50Hz transformers, become awfully lossy when the frequency is only few kilohertz.

2015/3/28However, one can convert to DC and then regenerate an AC at the desired frequency with some, perhaps insignificant loss. In fact, for some time, PS audio offered a device, for the high-end audio community that regenerated the AC supply with the option of
How does a higher frequency make the impedance of a capacitor lower
Answer (1 of 4): Unlike resistors, the impedance of a capacitor is a function of the frequency. The term impedance, has a different meaning in the case of a resistor and a capacitor. In a resistor, the electrons flowing through it are obstructed by the resident passive
High-frequency heating is also named radiofrequency/ dielectric heating, microwave IR heating. This is a thermal method, used for eliminating microorganisms. This heating method utilizes electromagnetic energy to warmth the products. This offers an additional fast consistent heat supply and also reduces the quality drop of the products.
What is Switching Frequency? The rate at which the DC voltage is switched on and off during the pulse width modulation process in a switching power supply. The switching frequency in an inverter or converter is the rate at which the switching device is turned on and off. Typical frequencies range from a few KHz to a few megahertz (20Khz-2MHz).

What are the advantages and disadvantages of a 50 Hz and a 60 Hz power supply? Why do countries prefer either of the frequencies
Answer (1 of 21): Historical decisions made in the past. The 50 Hertz system was developed in Europe and standardized by AEG as 40 Hz produced too much flicker in lamps. The 60 Hz systems is a bit more efficient, as less iron can be used in power transformers
The reactance of a capacitor is, `X_C = 1/(2pifC)`, where f is the frequency of the AC supply and C is the capacitance of the capacitor. For very high frequency, f, X C is very small. Hence, for a very high-frequency AC supply, a capacitor behaves like a pure
