Waves of different mode propagate independently, generally all modes above the respective cut-off frequency are propagable. You'll usually try to avoid higher modes by the waveguide transition design, also in some cases special mode filter elements. - - - Updated - - - I mean different mode waves of same fre
49 kHz cut-off doesn't sound completely wrong for a second order filter, if you'll want to avoid noticeable magnitude and phase deviation in the audio range. Another point is size minimization of filter components, particularly inductors. This might suggest not to reduce the cut-off frequency, even for a subwoofer. (...)
Hi guys I have a question about the understanding of Photodetector in photovoltaic-mode and their cut-off frequency. The frequence limited by the capacity of the Photodiode (example a PiN) and by the size of the load impedance. So it is possible to have a cut-off frequency at some MHz? In the most (...)
Is it feasible to achieve 1 MHz cut-off frequency through sallen-key active RC filter on chip? If possible, what should the minimum order of the filter be? Added after 2 hours 36 minutes: One More question regarding SK filter: What kind of stability issues one might encounter while d
I don't think you need to change your waverport size. First, define the cut-off freq of those modes. Use the rectangular waveguide formula to calculate the cut-off freq. Then set the number of modes allowed to propagate in your hfss setting. wlcsp hi wlcsp thanx for reply, it helps a lot. what should i do when i need to
After digitizing pass it through a digital low pass filter that will reduce the noise, set the cut of frequency depending on the signal frequency interested.
Can you clarify "very accurate" and other special requirements you may have such as tempco, cost, size, and power consumption? Maybe you could use an oscillator instead of a crystal. You may need to buy one that's custom cut to your required frequency, or use a programmable oscillator (beware higher phase noise).
Honey, I just shrunk the antenna! PORTLAND, Ore. ? A four-year skunk works effort at the University of Rhode Island in Kingston has cut the size of an antenna by as much as one-third for any frequency from the KHz to the GHz range. Using conventional components the four-part antenna design cancels out normal inductive loadi
