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 ...

Auto-detecting CAN-Bus bitrate
My team and me are developing our own CAN-Bus adapter. For now, based on the ESP32's integrated CAN-controller, later using an MCP2518fd. I wonder about the best way to auto-detect the configured ...

Why is the bitrate of infrared smaller than the bitrate of WiFi?
Infrared has a frequency of 300 GHz – 430 THz, while WiFi has a frequency of 2.4 GHz or 5 GHz.
As the frequency of infrared is greater than the frequency of WiFi, the transfer rate (bitrate) of IR ...

Maximum bit rate over a communication channel
Shannon formula C= B log (1+S/N)
Is this formula applied for baseband transmission only? or for both baseband and passband modulation? Can we apply it without any changes to any modulated signal? What ...

How Ethernet uses full bandwidth of the link if one host is sending more than one frame for different hosts? [closed]
I followed from this question.
We know that modern Ethernet is full-duplex. At the same time, we can send or receive the signal. Suppose I consider one LAN where multiple hosts are connected by ...

Baseband uses full bandwidth of the entire link or portion of the bandwidth?
We know that modern Ethernet is full-duplex. At the same time we can send Or receive the signal. Suppose I consider one Lan where multiple hosts are connected by different ports of switch.
Let's take ...

Why baseband uses full bandwidth of the signal where broadband uses portion of the bandwidth? [closed]
We know that broadband signal is full-duplex, for example television cable line where all TV channel is used portion of bandwidth not full bandwidth. And modern baseband is also full duplex but all ...

Feasible digital bit rate in SSB
Decades ago, I worked on a suppressed-carrier SSB transceiver with a carrier frequency of 8.8 KHz. The bandwidth was sufficient for speech communication, comprehensible but not high-quality.
For a ...

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 ...
