Title: Innovations of Randall L Baumbach
Introduction
Randall L Baumbach is a notable inventor based in Arnold, MD (US). He has made significant contributions to the field of communication systems, holding a total of three patents. His work primarily focuses on timing recovery schemes for burst communication systems.
Latest Patents
One of his latest patents is a timing recovery scheme for burst communication systems featuring a voltage-controlled oscillator (VCO). This innovative apparatus optimizes the sampling and digitizing of received data at various data rates. The VCO is phase-locked to a local frequency reference before data reception. A reference timing preamble is transmitted prior to the data, which is filtered and fed to the VCO, causing it to injection lock and become phase-aligned with the preamble. During data transmission, the VCO is allowed to 'free run' while maintaining a consistent frequency. A synchronous divider and multiplexer, responsive to the VCO, facilitate the selection of sampling clocks for multiple data rates. The divider is forced into a known state during VCO injection locking to ensure that the sampling clocks maintain the correct phase for optimal sampling. Additionally, the system includes monitoring means for the VCO frequency, providing indications if the frequency drifts beyond a predetermined threshold.
