The system has a device for taking a regular succession of samples from the signal waveform. A device reads the sample values into storage at a given speed for a fixed period and another device reads the values out of storage during the last part only of the fixed period and at a proportionally increased rate. The waveform presented to the system is an analogue waveform, and the values read out from the store are re-converted to analogue form in presenting the result. - The access store uses a number of store locations, which corresp. in to the number of data bits. The locations are connected to the main store at the first count of the time-compression sequence and when all the locations are connected, the timing sequence is completed. The arrangement which connects the access stores into the main store consists of an address counter to designate the corresp. locations. A unit generates the first time signal to increment the write address counter and connect the data bits into the corresp. store locations. |
