Recommended methods of measurement on receivers for television broadcast transmission. Part 2 : Electrical and acoustic measurements at audio-frequencies

This technical specification addresses a set of standardized procedures for evaluating television broadcast receivers, specifically focusing on the electrical and acoustic measurements within the audio frequency range. It establishes a consistent methodology to ensure that sound quality assessments are performed uniformly across different manufacturing contexts and testing environments. The document outlines precise measurement conditions, including signal levels, frequency response boundaries, and distortion parameters relevant to audio reproduction systems in receiving devices. By defining specific test signals and measurement configurations, it enables manufacturers and laboratories to compare performance data reliably. These guidelines cover aspects such as harmonic distortion, signal-to-noise ratios, and frequency response characteristics under normal operating conditions. The scope includes both theoretical definitions and practical implementation steps for conducting assessments. This framework supports the evaluation of how well a receiver processes audio information, ensuring compatibility and fidelity in broadcast playback systems without deviating from established norms for acoustic and electrical analysis.
