Abstract: An output signal pulse width error correction circuit and method wherein errors in a data signal conforming to a communications protocol having a prescribed duty cycle are corrected by monitoring a duty cycle of the data signal, comparing the duty cycle to a duty cycle reference voltage corresponding to the prescribed duty cycle, and adjusting a pulse width of the data signal to conform to the prescribed duty cycle of the protocol. An embodiment is shown that low pass filters the input data signal to introduce greater slope to the input data signal which is then compared to a pulse width control voltage in order to generate an output data signal. The pulse width control voltage is produced by integrating the output data signal to obtain an average value corresponding to the duty cycle of the output data signal and comparing the average value to a duty cycle reference voltage corresponding to the prescribed duty cycle for the communications protocol. Another embodiment directed toward an integrated circuit implementation is shown that converts the input data signal into complementary input data current signals, using current mirror circuits, which are used to drive complementary variable delay circuits. The pulse width control voltage is also converted into complementary error current signals which adjust the duty cycle of output data signal by controlling the variable delay circuits.

Abstract: A transmission system develops a binary encoded data train having a message and a header preceding the message. The data train is applied to a carrier frequency to modulate the carrier using FSK techniques. The header includes synch signals, one or more address signals, a message length signal and control signals separating the above signals. One or more personal receivers receive the message if responsive to one of the address signals in the header. An address signal may address a unique personal receiver, a selected group of or all such personal receivers. Each receiver is sequentially activated and deactivated, being activated to detect a synch signal. If synch signals are detected, the receiver remains activated to determine if an address signal identifies such receiver to receive the message. A received message is stored digitally and may be selectively displayed in alphanumeric characters when convenient for the recipient.
