The Error Probability Trainer brings out the concepts of noise in communication channel from statistical point of view. All Communications systems are to be designed so that the probability of error is minimised. A generator produces pseudo random binary sequence which acts as a signal. A random noise generator of variable amplitude is there. The signal and the noise are added to make the transmitted signal. The receiver correctly detects the binary sequence present in the mixture of the signal and noise,and the counter indicates the error count.
