What is relation between roll off factor bandwidth and bit rate?
The roll-off factor of a digital filter defines how much more bandwidth the filter occupies than that of an ideal "brick-wall" filter, whose bandwidth is the theoretical minimum Nyquist bandwidth. The Nyquist bandwidth is simply the symbol rate expressed in Hz: Nyquist Bandwidth (Hz) = Symbol Rate (Sym/s) However, a real-world filter will require more bandwidth, and the excess over the Nyquist bandwidth is expressed by the roll-off factor. Suppose a filter has a Nyquist bandwidth of 100 MHz but actually occupies 120 MHz; in this case its roll-off factor is 0.2, i.e. the excess bandwidth is 0.2 times the Nyquist bandwidth and the total filter pass-bandwidth is 1.2 times the Nyquist bandwidth.
What is the roll of bleeder resistance in LC filter circuit and what will happen if the bleeder resistor is not used in circuit?
jgfkf
What is gain roll off?
A: As frequency increases all amplifier exhibits losses due to internal capacity or internal devices frequency limit. At the hi end of the frequency the amplifiers begins to loose gain gradually as a function of higher frequency that is what roll off is.
What causes the gain of OP AMP to roll off after a certain frequency is reached?
A: Any amplifier will reach a frequency cut off point because of hindered circuit capability however the roll of bust be controlled especially when reaching oDB point must be at a -3 db roll off to prevent hi frequency oscillation
How High pass filter circuits works?
A High Pass Filter is an Electronic Filter that passes high frequency signals but Attenuates (reduces the Amplitude ) of Signals with frequencies lower than the cut-off Frequency
Which filter has the fastest roll-off?
chebyshev
Why higher value of roll off is disirable for a filter?
The higher the rate or roll-off, the higher the out of band attenuation.
Why higher value of roll of is disirable for a filter?
The higher the rate or roll-off, the higher the out of band attenuation.

How can I modify my MICROPHONE to filter background noise?
There are certain features on editing softwares such as Audacity or Logic Pro X that can help with this, but I would suggest using an actual filter, purchase on online, that surrounds the microphone! This will work the best.
How is the Asahi microscope used?
The Asahi microphone has to be powered by the dry cells for it to function. The Asahi microphone has the on and off button that either switches it on or off.
What Is A Pop Filter?
A: A pop filter is a filter that is placed in front of a microphone in a recording studio that keeps extra air from hitting the microphone when a vocalist sings. When singers use words that have the letter "p" or "k", "s", "f", or "b", they tend to use their diaphragm more and this forces air out of their mouth without them realizing it. That sound will hit the microphone and cause the recording to sound really windy (the same thing that happens when the wind hits a microphone) and that can be really bad for a professional recording.
How do you stop a microphone?
Pull off the plug.
How do you break a microphone?
Pull off the plug.
What is the roll of the liver?
to filter impurities out the body
Why is it easier to tear a paper towel off of a full roll than off of a mostly used roll?
A full roll is very sturdy, while a mostly used roll is more fragile. Therefore, when you go to pull the paper off the full roll, it comes off easily without you having to steady the roll...but if you want to tear paper off a mostly used roll, you'll have to hold the roll down before you tear it off so the roll doesn't fall. Basically, because a full roll is sturdier than a mostly used roll.
