The Serial Analog Memory — Its Application to Television
Integrated circuits which can controllably delay an analog signal have been developed and are finding a wide range of applications within the television and recording industry. Where the commonly used charge-transfer devices transfer a sample of the information through a series of storage cells and lose fidelity with each transfer, the devices described here store a sample of information on a given cell and transfer it only once during readout. The two devices treated are a 64-element serial analog memory (SAM-64) and a 100-element serial analog delay (SAD-100). The delay may be thought of as a special case of the memory where independent I/O is not utilized. Both devices are capable of sampling at rates in excess of 10 MHz with SNR better than 55 dB. Applications discussed include time-base correction, drop-out compensation and remotely controllable simulation of cable length.
