20190296782 · 2019-09-26 · ·

A receiver and a program capable of, when they have received a pulse noise together with a reception signal, improving quality of the reception signal are provided. A receiver according to the present disclosure includes a received-signal amplification circuit configured to amplify a monitoring received signal branched from a received signal, a gain control circuit configured to set a gain setting value for an AGC operation in the received-signal amplification circuit, the AGC operation being an operation for making an amplitude of an amplified monitoring received signal fall within a predetermined range, a pulse detection circuit configured to monitor a change in the gain setting value and detect whether or not a pulse noise is contained in the received signal based on whether or not the change in the gain setting value meets a predetermined condition.

Hybrid digital-analog automatic level control (ALC) using vector signal generators (VSG)
12047066 · 2024-07-23 ·

A hybrid automatic level control (ALC) system for controlling analog outputs. Within the ALC, a feedback loop passes from an analog circuit to a digital circuit and may provide the level of the analog output to the digital circuit. The digital circuit may use lookup tables to model the responses of analog devices but without associated errors and complications of the analog domain. Some examples of the modeled response include linear frequency responses of analog diodes and frequency responses of analog filters. Based on the received feedback and using the lookup tables modeling the responses, the digital circuit may drive a digital-to-analog converter interfacing the analog circuit to control the level of the analog output.
