Abstract— balanced ring modulator is a type of modulator that the diodes are arranged like a ring. In balanced ring modulator, there are also transformers and the carrier. This type of modulator is like bridge modulator. However, the arrangement of the diodes are different from bridge rectifier either in clockwise or anticlockwise. For the operation of the balanced ring modulator, the output of the waveform produce by balanced ring modulator depends on the arrangement of the carrier. This is because the polarity of the carrier will affect the flow of modulating signal through the diodes. The outputs are made up of two signals, one signal shifted up by carrier frequency signal and the other signal is shifted down by frequency carrier. Balanced ring modulators are widely use in musical instrument like guitar and radio receivers.
Keywords— balanced ring modulator, modulating signal, carrier signal, output waveform, amplitude
I. Introduction
We as a group of telecommunication engineer in the established telecommunication company have been invited to participate in one seminar called “Principle Communication and Communication System”. In the seminar, our group has been responsibilities on a project to design a balanced ring modulator circuit which is need to comes up with proposal and present it in a technical report. In order to design the balanced ring modulator circuit, there have some procedures that are needed to consider in process to obtain the actual output. Basically, the circuit is constructed with diodes and transformers and it has two inputs: a single-frequency carrier and the modulating signal which of this two inputs which may be a single frequency or complex waveform. The balanced ring modulator will operate
