Abstract :
Test instrumentation has been developed for simulating the principal types of transmission impairments that will be encountered on voice-frequency telephone circuits. Such impairments include delay and attenuation distortion, frequency shift, phase and amplitude hits, interfering tones, and noise. This test equipment, together with conventional random-data signal generators and error comparators, makes possible the evaluation of data systems with a wide range of transmission characteristics.
