摘要： A customizable communications bus control gate array for facilitating communications between devices on two disparate digital communications channels. The gate array has a mask programmable integrated circuit with two I/O interface devices which are respectively connected to two different communications channels. The gate array also has a translating device connected to each of the I/O interface devices for translating electrical signals therebetween. Logic control is also provided and connected to both of the I/O interface device and to the translating device for controlling operations thereof so that predetermined communications requirements between both of the disparate communications channels are satisfied.

摘要： Variable sample rate converter by convolution of input data samples with an impulse response to produce output samples with the impulse response values generated by interpolation from a table of oversampled values with the oversampling rate lower for outlying lobes of the impulse response.
