Title: Alan R Bloom: Innovator in Digital Modulation and Analog Signal Processing
Introduction
Alan R Bloom is a notable inventor based in Santa Rosa, California. He holds 2 patents and has made significant contributions to the fields of digital modulation and analog signal processing. His work has been instrumental in advancing technologies that are widely used in communication systems.
Latest Patents
One of his latest patents is for a digital baseband modulator adaptable to different modulation types. This innovative modulator features a flexible architecture that can easily adapt to various digital modulation types. It includes a symbol builder that maps input data to a series of modulation states, which are represented as state indexes. The design incorporates a pair of digital filters that provide both up-sampling and filtering functions, utilizing random access memory (RAM) for efficient processing. The filtered output is then converted to an output sample rate suitable for digital-to-analog converters (DACs).
Another significant patent by Bloom is for an analog ramp generator with digital correction. This invention uses an analog ramp signal to control the frequency of a swept radio-frequency (RF) test oscillator. To enhance ramp accuracy, the analog ramp signal is periodically compared to a digital ramp signal generated by a DAC. This comparison allows for corrections to be made, ensuring the precision of the analog ramp signal throughout the sweep process.
