Title: Joan Mercadé: Innovator in Signal Processing Technology

Introduction

Joan Mercadé is a prominent inventor based in Barcelona, Spain. She has made significant contributions to the field of signal processing, particularly through her innovative patents. With a total of 2 patents, her work has advanced the technology used in waveform generation and signal manipulation.

Latest Patents

One of her latest patents is titled "Asynchronous time-interleaved waveform generator using harmonic mixing." This invention involves a waveform generator that splits a digital input signal into multiple split signals. Each split signal maintains a frequency bandwidth similar to that of the original digital input signal. These split signals are then mixed with associated digital harmonic signals to produce mixed digital signals, which are converted to analog signals at an effective sample rate that differs from the first order harmonic signal. The resulting mixed analog signals are combined into an output signal with a bandwidth greater than that of at least one of the digital-to-analog converters (DACs).

Another notable patent is "Signal generator and user interface for adding amplitude noise to selected portions of a test signal." This invention allows a signal generator to create amplitude noise on a chosen segment of a test signal. A user interface enables the selection of the test signal segment and the associated power level for applying amplitude noise. The signal processing unit compiles the selected power level with the test signal, generating digital data that represents the test signal with amplitude noise in specific segments.
