Granted: 1992-05-13
Abstract: When a time-sequential signal such as an analog or digital data signal is recorded on a disc-shaped recording medium (11), the transmission rate of the digital data is determined or the time-sequential analog signal is sampled at a predetermined sampling frequency to obtain time-sequential digital data which is sequentially recorded on the disc-shaped recording medium (11). The rotational speed of the disc-shaped recording medium (11) is controlled in response to the transmission rate of the time-sequential digital data. The transmission rate is recognised by a speed control signal generator circuit (36) either from clock signals derived from self-clocking digital data supplied to an input terminal (31D), or from a separate signal indicative of the transmission rate supplied to a terminal (31R). In the case of an analog signal supplied to an input terminal (31A), an analog-to-digital converter (32) sets the transmission rate and this is detected by the speed control signal generator circuit (36). The rotational speed of the disc-­shaped recording medium (11) is controlled by controlling the speed of a driving motor (21) by means of a phase comparator circuit (23), an integrator circuit (24) and a motor drive circuit (25).

Abstract: A time division multiple access (TDMA) radio system conveying a quadrature phase shift keying (QPSK) modulated data signal is disclosed. In order to overcome multipath distortion and phase variation introduced by the radio channel, a synchronizing portion of a TDMA timeslot is transmitted in only one vector of the QPSK modulation. The system utilizes the one vector synchronizing portion to develop a channel profile estimate which is applied to the received message portion of the QPSK data signal to compensate for the multipath distortion and phase variation during one TDMA timeslot.
