In a receiver, a system and method are disclosed for providing improved detection of data from a transmitted sequence of pulse width modulated (PWM) pulses. The disclosed system includes a pulse detector having an adjustable critical duty cycle for distinguishing between first and second pulses based upon their respective long and short duty cycles at which they are received. The disclosed system further includes an element which determines the duty cycle of the received pulses and an element which adjusts the critical duty cycle based on the duty cycle which is so determined. The duty cycle may be determined by determining the correspondence between information obtained from an initial pulse sequence and reference information at the receiver. In the disclosed method, the duty cycle of pulses in an initial sequence is first determined and then checked against a predetermined limit. If the duty cycle falls outside the limit, the critical duty cycle is adjusted prior to further pulses being detected.

Receiver for pulse width modulated transmissions

A system and method for storage and communication of information between at least one first information containing terminal and a second terminal. The system and method includes generating a random number within the first terminal in response to receipt of a begin signal from the second terminal, and comparing the random number to a count incremented and maintained by a digital counter within the first terminal. When the random number is equal to the count, the first terminal transmits a request to transmit signal to the second terminal. If the second terminal responds with a first acknowledgment, the first terminal then sends an information containing signal to the second terminal. If the information containing signal is correctly received, the second terminal responds by transmitting a second acknowledgment which is received by the first terminal.
