A programmable sound generator (PSG) is a sound chip that generates (or synthesizes) audio wave signals built from one or more basic waveforms, and often some kind of noise. PSGs use a relatively simple method of creating sound compared to other methods such as frequency modulation synthesis or pulse-code modulation. [1]
A sound test is a function built into the options screen of many video games.This function was originally meant to test whether the game's music and sounds would function correctly (hence the name), as well as giving the player the ability to compare samples played in Monaural, Stereophonic and later Surround sound.
When a specific test is applied to a sample of size n produced by an RNG, the p-value of the test usually will remain reasonable as the sample size increases until the sample size hits n 0, say. After that, the p-value diverges to 0 or 1 with exponential speed. Module 4 allows the researcher to study the interaction between a specific test and ...
A noise generator is a circuit that produces electrical noise (i.e., a random signal). Noise generators are used to test signals for measuring noise figure, frequency response, and other parameters. Noise generators are also used for generating random numbers. [1]
A random stimulus is any class of creativity techniques that explores randomization. Most of their names start with the word "random", such as random word, random heuristic, random picture and random sound. In each random creativity technique, the user is presented with a random stimulus and explores associations that could trigger novel ideas.
A randomness test (or test for randomness), in data evaluation, is a test used to analyze the distribution of a set of data to see whether it can be described as random (patternless). In stochastic modeling , as in some computer simulations , the hoped-for randomness of potential input data can be verified, by a formal test for randomness, to ...
Frequency domain, polyphonic detection is possible, usually utilizing the periodogram to convert the signal to an estimate of the frequency spectrum [4].This requires more processing power as the desired accuracy increases, although the well-known efficiency of the FFT, a key part of the periodogram algorithm, makes it suitably efficient for many purposes.
Random test generators (often abbreviated RTG or ISG [1] for Instruction Stream Generator or Instruction Sequence Generator [1]) are a type of computer software that is used in functional verification of microprocessors. Their primary use lies in providing input stimulus to a device under test.
