How to compute the energy efficiency in bits/s/watt
The energy efficiency (EE) in wireless communications is usually calculated as the ratio of data rate to power consumption: how many data (in bits per second) are delivered per consumed power (in ...

Data rate for an ASK modulation [closed]
A telephone line with a bandwidth of 3 kHz and an SNR of 6 dB. I am asked to calculate the maximum bitrate on this line and the error probability, knowing that ASK modulation is used.
For ASK ...

Why does PCIe still hold on to 'transfers/second' instead of bits/second or symbols/second?
I think it is kinda all covered in the title. To my (incomplete) knowledge, PCIe is the only modern bus that still expresses its rate in transfers per second. Is there, apart from 'tradition' any ...

How to compute data rate I can reach with my design?
I implemented a modulator for a transmitter, which sends baseband modulated signal.
The transmitter has the following parameters:
datarate : 520 Ksps (min), 64,44 Msps (max)
Bandwidth: BW = 56 MHz (...

AD9361: how to compute datarate and configure filters
I will use AD9361 as a transmitter of a modulated baseband signal. The modulated baseband signal is implemented in FPGA/SDK.
AD9361 has real-time bandwidth of 56MHz but we have maximum 61.44 MSPS data ...

ADXL345 Accelerometer data rate vs bandwidth
I recently started working with the ADXL345 Accelerometer and got a bit confused on what's the difference between the data rate and bandwidth.
From the ADXL345 datasheet p14, we can see the different ...

Maximum Ethernet bandwidth through a slip ring
I'm trying to understand what would prevent a 1 GbE non-optical slip-ring from transmitting 10GbE, 40GbE or even 100/200/400GbE. They all have 'metallic'/copper variants (backplane or short cable) and ...

How can Google Fiber make a difference since most of the mediating wires out there are copper?
Optic fiber sends more data more quickly. But if you look at the Google Fiber map you will see that only the local connections are optic. The rest of the world is almost entirely copper, right? So won’...

Expected SDRAM access speeds?
I would like to get an idea of how fast SDRAM accesses should be.
If I have a 32-bit ARM based processor running at 500MHz accessing an SDR sdram device clocked at 166MHz, what sort of read/write ...

Why doesn't higher frequency mean higher data rate?
My question is very primitive :) I've read multiple articles today and answers here, on Stack Exchange, but still don't understand one thing. Why doesn't frequency itself affect data rate in mobile ...

What is the meaning of Output data rate of Bosch BMI270?
what is the meaning of ODR (output data rate)
BMI270 says it has 1.6kHz for accelerometer ODR
does it mean internal registers update rate is 1.6kHz
or
1.6kHz/(16bit x 3) = 33Hz ? (here 3 is, 3 ...
