Title: Pieter Meijer: Innovator in FM Radio Technology
Introduction
Pieter Meijer is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of FM radio technology, holding a total of 4 patents. His innovative designs have advanced the way FM radio receivers operate, enhancing the listening experience for users.
Latest Patents
One of his latest patents is the diversity FM radio receiver. This invention comprises two tuners that simultaneously tune to the same FM channel. To avoid disturbances between the local oscillator signals of the tuners and to utilize standard IF filters, one tuner operates with high-side LO injection while the other uses low-side LO injection. The two IF-signals from the tuners are processed through complex mixers with oppositely rotating phases to equalize the frequencies for diversity operation.
Another significant patent is the antenna diversity receiver. This system includes an antenna device with multiple FM antennas and a controllable switching circuit. The circuit sequentially switches through one of the FM antennas via an antenna cable to a receiver upon receiving a switching control signal. The receiver features a multipath detector linked to a pulse generator, which generates a pulse signal used as the switching control signal. To ensure accurate detection, the pulse generator is connected to a pulse shaper that converts the pulse signal into a pair of pulses with opposite polarities.
