| description | Tape recorder apparatus compatible in communications systems with cryptographic units which are generally adversely affected by excessive tape jitter and speed variations. Long term, gross tape speed control is provided by a high-compliance, low-mass drive system which follows inversely synchronization (sync) data recorded on the tape. Data tones are demodulated and clocked into an input register at the recorded sync rate. By means of fine dump control, while the input register is accumulating, an outputting register precisely clocks out bits at a rate acceptable to the interface units. The registers are alternately switched from accumulate to dump function. |
