Abstract: 1,203,659. Digital transmission systems. NIPPON ELECTRIC CO. Ltd. 22 Dec., 1967 [29 Dec., 1966], No. 58534/67. Heading H4P. A code converter converts m-level code to (m+1) level code in which the average D.C. level is zero. As described, 4-level input data b, Fig. 1, is converted to 5-level data i. The input data feeds a three-digit shift register which is connected to an adder which develops the level-sum of the stored digits-the levels of the data b are shown at a, grouped in 3-digit groups, and the level-sum of each group is shown at c. If the level-sum is negative the content of the register is replaced by a corresponding 3-digit 5-level signal which has at least one digit in. the lowest level (i.e. -2), this level not existing in the 4-level code. On the other hand if the level-sum of the stored digits is zero or positive no conversion takes place. The register contents e are read out via an inverter to a transmitter, the inverter being enabled under control of a threshold circuit. The threshold circuit is fed by the level-sums f of the 3-digit groups read from the register and forms a sum-total g. When addition of the level-sum of a group would make the total exceed a level ho that level-sum is subtracted and the threshold circuit output h enables the inverter so that the corresponding 3-digit group is inverted, the resultant transmitted signals being i.

Title: Swept oscillator systems
IPC: H03G5/00
Filed: 1979-05-29
Abstract: An oscillator is controlled by a multi-bit parallel digital signal to sweep across a frequency band, for example for driving a test mounting for vibration testing of components. The output of the oscillator is filtered by a filter (20) whose centre frequency is set by R-C networks, whose resistive components comprise parallel groups of resistors, each in series with a switch controlled by one of the bits of the digital signal. In this way, the centre frequency of the filter tracks the oscillator frequency. The digital signal can be used to control other circuits in a similar manner, for example to vary the gain of an amplifier 28, 30 to mimic the response of an integrator. The oscillator 16 includes a crystal oscillator feeding separately a chain of counters and rate multipliers, the latter also receiving the counter's outputs and a combination of the multiplier's outputs provides the swept frequency signal. <IMAGE>
