ParticipantHi everyone,
Can someone please explain What is threshold in BER analyzer? Does it vary from design to design ?
Thankyou

Remo De Suza
ParticipantHi Gaurav.
The threshold is the value based on the received bits level compared to which the bit is detected. If the received bit amplitude is less than the threshold, the bit is detected as a logic “0”, and if the bit amplitude exceeds that of the threshold, the bit is detected as a logic “1”. I hope it helps.

SpectatorHELLO GAURAV..
The definition given by Remo can be one of the many definitions of threshold.. You can refer to the link provided below by Remo it will help you i suppose.

ParticipantHi Gaurav,
threshold is very essential parameter to be set in the tranmission channel.
if threshold is smaller, then there is great possiblity of heaving eerors in system because of noise power greater than threshold.
if threshold is larger, there is possibility of loss of bits(i.e again error) in reception, because bit power can be less than threshold because of channel attenuation thus threshold is to be optimized for minimum BER.Thanks

ParticipantHi Gaurav,
Threshold is important parameter in case of eye pattern.
We analyse the performance of a communication system is its Bit Error Rate (BER) measured at the receiver.
However BER is pass/fail in nature (i.e., a threshold of BER is set and we check if the system BER is greater
than or less than this threshold) and it conveys nothing more.
We find probability of occurrence of 0 or 1 with help of threshold, because first we set threshold value then we the value of signal greater than this threshold is detected as 1 otherwise 0.Here are links you can refer to:

ParticipantHi all,
I agree with Remo The threshold is the value based on the received bits level compared to which the bit is detected. If the received bit amplitude is less than the threshold, the bit is detected as a logic ?0?, and if the bit amplitude exceeds that of the threshold, the bit is detected as a logic ?1? Also try to see the links where it has already been discussed on the forum..
