The development of the high switching frequency static converters based on Wide-Bandgap Semiconductors (GaN and SiC) requires EMI filters with high-performance for aeronautic applications. It is well known that the high frequency parasitic couplings between passive components have a negative impact on EMI filter attenuation. In this …

In many cases, EMI filter plays a key role in EMC design. However, the performance of EMI filters, especially in high frequency, is often different from previous estimates. Based on this situation, this paper first theoretically calculates the performance of EMI filter, and then analyzes the effect of the parasitic parameters of each component of the filter and its …

We have developed a diamond SAW resonator capable of operating at frequencies over 3 GHz using a SiO(2)/ interdigital transducer (IDT)/AlN/diamond structure. This structure is expected to have a high Q value and a zero temperature coefficient of frequency (TCF) over 3 GHz, based on the high acoustic …

Technically, there is no such thing as an active high pass filter.Unlike Passive High Pass Filters which have an "infinite" frequency response, the maximum pass band frequency response of an active high pass filter is limited by the open-loop characteristics or bandwidth of the operational amplifier being used, making them appear as if they are …

The frequency ω0 is called the corner, cutoff, or the ½ power frequency. Also, by considering the definition of the dB we have () 20log(()) dB Hω = Hω (1.4) Which at ω=ω0 gives () 3 dB Hω =−dB (1.5) And so the frequency ω0 is also called the 3dB frequency. For our example RC circuit with R=10kΩ and C=47nF the Bode plot of the transfer …

As with low-pass filters, high-pass filters have a rated cutoff frequency, above which the output voltage increases above 70.7% of the input voltage. Just as in the case of the capacitive low-pass filter circuit, the capacitive high-pass filter's cutoff frequency can be found with the same formula:

Band-pass filtering is used most commonly, because a seismic trace typically contains some low-frequency noise, such as ground roll, and some high-frequency ambient noise. The usable seismic reflection energy usually is confined to a bandwidth of approximately 10 to 70 Hz, with a dominant frequency around 30 Hz.

Any high frequency signals applied to the low pass filter circuit above this cut-off frequency point will become greatly attenuated, that is they rapidly decrease. This happens because at very high frequencies the reactance of the capacitor becomes so low that it gives the effect of a short circuit condition on the output terminals resulting in ...
