Self clock synchronization in NRZ-I encoding
I was going through NRZ-I encoding technique, somebody mentioned that long stream of 0's will cause loss of synchronization in NRZ-I encoding scheme. But how?
What I understand is the receiver should ...

Positionally aware 360° (or beyond) motor (DC or stepper)?
Most servo motors out there are driven within 180° (at least hobby ones). There are more bulky and expensive servos out there as well. Since, I have tight space constraints, I am looking for a ...

How do we change the digital encoding method of a signal? (eg. From Unipolar NRZ to Polar NRZ)
We have different digital encoding methods like Unipolar, Polar, Bipolar, Manchester. I was working with stm32f411re and I saw USART uses Unipolar NRZ. So how do we change this encoding methods?
I ...

Manchester encoding clock rate
The statement given is
Bi-phase Encoding
The signal level is checked twice for every bit time, both initially and in the middle. Hence, the clock rate is double the data transfer rate and thus the ...

Why use 128b/132b line coding?
Some background/research: for various reasons, many protocols use 8b/10b encoding, which encodes 8 bits of data in 10 bits of line code. However, doing so adds 25% overhead to the number of bits ...

Hamming code question
Suppose we have m data bits and n parity bits. In order for the Hamming code to function: $$m+n<2^n-1$$
If we have 3 parity bits we can have up to 4 data bits. But lets say we don't have 4 data ...

Digital data to digital signals with Non return to zero(NRZ)
NRZ codes share the property that voltage level is constant during a bit interval. High level voltage = bit 1 and Low level voltage = bit 0.
A problem arises when there is a long sequence of 0s or 1s ...
