Timing Arduino response with ADXL345 accelerometer's data rate
I'm currently working on a system that calculates the velocity by integrating the values of the acceleration.
I'm using the ADXL345 accelerometer with a ESP32, and so far, everything's going good, i'm ...

Data Lines on VME64 Bus
I am learning about the VME64 bus. It has only 16-bits of data bus on its P1 connector while no data pins on P2 connector.
Does it means that VME64 is actually a 16-bit bus?

Signal to noise ratio for a non-physical property
The signal to noise ratio for a voltage, current, or power is easy to understand, but how do I calculate the SNR when the signal is not a physical property, but instead an abstract quantity?
I'll try ...

Required Bandwidth for ASK
In Amplitude Shift Keying, the bandwidth required is given by \$B=(1+d)S\$ where B is bandwidth, S is the signal rate, and d is a value of either \$0\$ or \$1\$.
But how could the required bandwidth ...

Relationship between sampling rate and number of levels/bits in PCM
It is said in the books that increasing the levels of quantisation codes in Pulse Code Modulation, or in other words increase the number of bits, could give a better signal.
I understand that having ...
