Strictly speaking, noise is a composite of a great number of signals at many, varying frequencies. It is a random quantity which generally has no regular or repetitive character. Although it is usually an unwanted quantity, noise may be used to analyze the performance of an audio system. A noise generator is, therefore, indispensable for much work in an audio workshop. Unfortunately, many amateur audio enthusiasts find the price of noise generator beyond their means. This is an affordable, small noise generator that is easy to build.
