摘要:
The design of a real-time analyser for performing fast Fourier transforms is described. Data are gathered at regular intervals without breaks for servicing the purpose-designed Fourier computer, which is used at the maximum speed permitted by this device. Three DMA devices are used to perform input, output and service of the Fourier computer. Separation of the real and complex parts and bit reversal are carried out by unusual wiring of the DMA devices to achieve the necessary speed with relatively few components.

摘要:
Practical concerns such as cost, reliability and testability in electronic systems design receive scant attention in some of the establishments responsible for the education and training of engineers. The paper suggests ways in which the educational needs of designers and test engineers in the field of computer technology might be met more effectively.
