Calculate the time taken to transmit the file over the wireless link

AI Thread Summary
To calculate the time taken to transmit a 16 MB file compressed with a ratio of 4, first determine the size of the compressed file, which is 4 MB (16 MB / 4). Next, convert this size into bits, resulting in 32 megabits (4 MB x 8). With a maximum data rate of 1.2 Gbps and a throughput of 60%, the effective data rate is 720 Mbps (1.2 Gbps x 0.6). Finally, divide the total bits by the effective data rate to find the transmission time, which is approximately 0.044 seconds, or 44 milliseconds, when rounded to two significant figures. This calculation provides a clear understanding of the transmission time over the wireless link.

Hello,
I've got this question:

A 16 MB file is compressed using a compression ratio of 4. The resulting compressed file is transmitted over a wireless connection that offers a maximum data rate of 1.2 Gbps. If a throughput of 60% can be achieved, and assuming there are no other transmissions occurring at the same time, calculate the time taken to transmit the file over the wireless link. Give your answer to 2 significant figures.

I thought about Shannon's formula, but it's completely foggy ...
Please could you help me?

Thanks

No other information is required, everything you need is provided in the problem statement.
 
...please could you explain me the process?
Thanks
 
Break it into steps.
1. How many bits must be sent?
2. What is the data rate?
3. How long does it take to send the data at that rate?
 
Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'
(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
