cutoff frequency

[′kət‚ȯf ‚frē·kwən·sē]
(electronics)
A frequency at which the attenuation of a device begins to increase sharply, such as the limiting frequency below which a traveling wave in a given mode cannot be maintained in a waveguide, or the frequency above which an electron tube loses efficiency rapidly. Also known as critical frequency; cutoff.

For existing designs using Linear Technology's LTC6804 battery stack monitor, the LTC6811 is a dropin replacement with additional filter cutoff frequencies, added passive and active balancing control features, new ADC commands and enhanced fault coverage for functional safety.
Enhanced Filter Flexibility and Increased Acoustic Response Control Additional enhancements to the APx software suite include a more flexible choice of filter settings in the signal path, allowing a wider range of cutoff frequencies and improving the user's ability to fully explore the device under test.
Attempts to circumambulate this irrelevant result by introducing cutoff frequencies either at the Planck length or at an arbitrary energy of 100 GeV, are hardly acceptable.
We selected four different cutoff frequencies, including three practice frequencies (0.
Newton Howard, Oxantium Venture's Managing Director commented on the investment, "With power densities 100 times greater than silicon and 20 times greater than gallium arsenide, intrinsic cutoff frequencies in the terahertz, inexpensive growth, and the ability to integrate with CMOS, we believe that RF Nano has the potential to radically extend current analog and mixed signal capabilities and open up entirely new product areas in the electronics industry that to date have been limited by the performance and cost of traditional silicon and GaAs solutions.
The setting of the cutoff frequencies is changed after the published specification of the transmission system operator Inverter list for distribution system operators; 50.
With traditional filter architectures, there is a tradeoff between low levels of capacitance -- which are necessary to achieve higher cutoff frequencies -- and reduced levels of filter attenuation.
Featuring true 2:1 Mux inputs for YPbPr or RGB inputs and triple 6th order filters with selectable 30 MHz, 15 MHz or 8 MHz cutoff frequencies, this device accommodates the full range of worldwide video formats.
The Praetorian III architecture utilizes a six pole pi-filter topology and features high cutoff frequencies, high levels of attenuation and robust ESD protection up to 15kV contact discharge consistent with the IEC 61000-4-2 level 2 standard.
The FMS6407 features a triple 6th order filter with selectable 30MHz, 15MHz or 8MHz cutoff frequencies, making this device flexible enough to be used in a broad range of video applications.
Groundbreaking Praetorian process technology allows the integration of inductors with capacitors and ESD protection diodes in a single chip design, providing superior EMI filtering, high cutoff frequencies, minimal insertion loss, sharp rolloff and greater levels of attenuation at high frequencies.
High cutoff frequencies of up to 400 Mhz -- A broad stop band ranging from 800 MHz up to 3 GHz that covers all wireless communication frequencies -- Superior signal integrity with rise times as low as 2ns, which cannot be achieved with RC filters -- Minimal insertion loss (<-2dB).
