USB Hub bandwidth problem [closed]

I will use a Beaglebone Black with a powered USB Hub to control a USB Microphone (PCM2912A) and a USB HDD. The task consists in recording and writing the Audio directly into the HDD... Will I have ...

frequency allocation for telecommunication companies

For a high bit rate in data communication we need a high bandwidth. Suppose there are hundreds of carriers in a particular region and they are all allocated microwave frequencies. Minimum spacing ...

Noise control in op-amp circuit design by using low spec op amps

I have a rather strange problem. I have a breadboard circuit on a double sided PCB with plenty of ground plane and a good well decoupled power supply. I am amplifying a small medium frequency signal (...

Practical Limit of Feedback Control Systems WRT Bandwidth

In a digital feedback control system, I'm interested in the practical limit of what the correctable bandwidth is. For example, given a very simple system: A sensor can sample a simple X position ...

Merit and meaning of fractional bandwidth

What is the merit of fractional bandwidth? $$f_{fractional}=\frac{f_{higher}-f_{lower}}{f_{mid}}$$ The same absolute bandwidth will have a smaller fractional bandwidth, if the mid frequency is ...

Transimpedance amplifier bandwidth

I'm planning to use an Avalanche Photodiode (APD) to perform sequential light sensing - something around 100 readings under a minute. From my calculations this implies a frequency of around 1.67~2Hz. ...

Using filters to reduce bandwidth of received signal

I am doing some radio work, and I assume you can use a bandpass filter to reduce the bandwidth of a received signal. The application is modifying schematics for a FM broadcast receiver to a 5-25 kHz ...

The bandwidth Ω of a low-pass signal f(t) ↔ F(ω)

I'm not sure about the answers to the two parts of this question: The bandwidth Ω of a low-pass signal f(t) ↔ F(ω) is defined by the constraint:  \frac{1}{2\pi } \int_{- \Omega }^{\Omega } \...

finding out the bandwidth of m(t)*m(t) if the bandwidth of m(t) is a known quantity

m(t)*m(t) in time domain is equivalent to the convolution of m(w) and m(w) in frequency domain.Thus if the bandwidth of m(t) is a known quantity then how is the bandwidth of m(t)*m(t) is determined?

Choosing Oscilloscope with appropriate bandwidth for Jitter analysis

Can someone give me a rule of thumb of choosing Oscilloscope with appropriate bandwidth for the Jitter analysis of clock signals? What device is highly preferable: spectrum analyzers, frequency ...

Does the fundamental frequency affect the bit rate on a wire?

This is from the book Computer Networks by Tennenbaum: The bandwidth is still the width of the band of frequencies that are passed, and the information that can be carried depends only on this ...

Why more bandwidth means more bit rate per second? [duplicate]

According to this link ( and some other sources I have found ) more bandwidth on a wire means more bit rates per second... Can someone try to explain why this is so as simple as possible? This is ...

Does an Oscilloscope's bandwidth need to match or exceed the microcontroller's/processor's clock speed?

Looking to buy an oscilloscope for home use, I've seen the questions on here in regards to bandwidth. I'm interested in prototyping microprocessors with clock speeds 800+ MHz, but I shouldn't need an ...
