Bit Rate vs Data Rate
So in short, the higher the transmission rate (bandwidth), the higher frequency in cable is required. This also relates to the encoding scheme used, as in PAM 5. To be brief, bandwidth is the theoretical speed of data on the network, for her school assignment on hers, your connection is going to be painfully slow. Part 1 lays out Shannon's law for channel capacity, and explains how bandwidth varies with signal power, noise, and interference.
Sometimes you will see bandwidth used to refer to radio frequencies instead of computers - we won't go into that. Nowadays, it's usually about computers, and how many bits of information we can theoretically transmit in so much time - for example bits per second.
Nyquist formula: relating data rate and bandwidth
Since those numbers get really big really fast, it is common to use big chunks like 1, bits per second kilobits or 1, bits per second megabits. Those are abbreviated Kbps kilobits per second and Mbps megabits per second. More About Throughput When throughput is mentioned, practical realities are involved, not just theoretical speeds.
Throughput can only send as much as the bandwidth will allow, and it's usually less than that.
Factors like latency delaysjitter irregularities in the signaland error rate actual mistakes during transmission can reduce the overall throughput. Think of bandwidth as your shiny new arteries with blood flow at its best, whereas throughput is what your blood flow looks like after all that cholesterol in your bacon plugs them up.
Bandwidth vs. Throughput
This is a great question. Then, you must load a disk image onto the testbed nodes. From the testbed console, run: If you are using WITest note that there is no space around the comma: This process can take minutes. Don't interrupt it in middle - you'll just have to start again, and it will only take longer. If it's been successful, then once the process finishes running completely you should see output similar to: Then, turn on your nodes with the following command: Prepare your receiver Open a new terminal window, and run the following command to tunnel the ShinySDR ports between your laptop and the receiver node: If you are using WITest note: Then, in that terminal window which should now be logged in to your testbed consolelog on to the receiver node: If you are using WITest: Configure your Shiny window as follows: Click on the "hamburger" icon in the top left corner to open the menu, if it isn't already open.
Un-select the "Frequency DB" display to hide that display if it is showing. Select the "Radio Config" display if it isn't showing. Note the "Gain" slider in the "Radio Config" section.

You may have to increase the gain later if you aren't able to see the transmission in the ShinySDR window. Check the "Use DC Cancellation" box, but don't worry if it doesn't stay checked.
Bit rate is the number of bits per second of footage, measured per frame or field, also expressed as bits per second. The common units for both are: One of the key features of an uncompressed raster file like a TIFF image, e. The first frame is all white, the second is all black, and the next three have totally different colors and images. Yet, because of the way the file system is defined, all five frames will have the same size. My bit rate is 7.
Okay, so if they share the same units, and sound the same, and have the same values, they must be the same, right? Each frame will have the same number of bits. What if a compression algorithm could be made smart enough to know when pixels contain redundant data?
If it sees a frame with lots of colors and information, it will allot this frame a higher number of bits.
When the frame contains less data it will allot this frame a lower number of bits.
