Title: Recovery circuit to derive clock signals from data bits - uses oscillator which functions at several times nominal bit frequency
Inventor: WELWARSKY WALTER DIPL ING
IPC: H04L7/033
Filed: 1979-09-01
Abstract: The circuit comprises a crystal oscillator (11), a frequency divider (12) which produces signals (G,Gbar) at n times the nominal bit frequecy, three flip-flops (14,15,16), a programmable multiplex unit (17) having signal inputs marked 0-7 enabled for read-out at the multiplex output (Y) by bit inputs A B C. This output is applied to a divide-by-n circuit (18) producing the desired clock output (C). The multiplex program input is derived from the data bit stream, delayed by one clock pulse G, in the shape of output from a bistable (15) (A) and a further signal again delayed by clock pulse period (B); and finally by the synchronised clock output, (C). Inputs (1,2) are G bar inputs (0,3,4,7) are G, and inputs (5,6) are at earth potential. This may be modified by making also inputs (2,6) equal to the clock; the change thereby obtained affects the phase angle of the active clock edge versus the rising or falling data bit edges.

Title: Digital telephone subscriber station with link to analogue exchange - has frequency gate for digital speech processor using electronic switches responsive to logic level
Inventor: STREHL HERBERT DIPL ING
IPC: H04M11/06
Filed: 1980-03-07
Abstract: To provide an existing analogue speech channel telephone subscriber with the option to communicate also with digital telephones, and/or to increase the utilisation of the modern large bandwidth telephone lines, a frequency gating circuit (FW) is added by which the high digital bit rate is branched into a digital processor unit (D) whereas the analogue signals are branched into a largely traditional telephone circuit (A). The digital unit (D) comprises a sending portion (DS) and a receiving portion (DE). Electronic switches (UM,UH) responsive to a logical level (u) input produce the changeover from the analogue to the digital section. For producing the bit rate for the digital encoder (CO) a resident oscillator may be provided. Alternatively, the digital sending bits may be derived from the received bit rate by placing the sending bits into the receive bit intervals. An alternative is pseudoternary partial step processing in the send/receive circuits (DS,DE). Or, the speech signals of the microphone may be precoded in a delta modulator and the received signals decoded in a delta demodulator. There are also connector outlets (gas, gae) for the sending/receiving of data.
