Define HRQ?
The hold demand output requests the access of the system bus. In non- cascaded 8257 systems, this is linked with HOLD pin of CPU. In cascade mode, this pin of a slave is linked with a DRQ input line of the master 8257, whereas that of the master is linked with HOLD input of the CPU.
What is the expected peak demand for a transformer feeding the following loads? Connected kVA
Q. Sketch a typical circuit for a 2-input, 4-output decoder.
Detection and Handling of Gas Leakage : If you are using a toxic gas or have a store for it you must have some devices to indicate the leakage, if any. Though numerous monitoring
