Audio mixing is the process of combining multiple audio channels into one or more audio channels. In this process source signals, frequency content, dynamics, level

Mobile communication is an emerging technology these days. GSM is the acronym for Global System for Mobile Communication. GSM module is wireless modem that transmits

Audio crossover is an electronic filter used in audio applications to send the appropriate signal to the speakers or drivers. Most of the speaker drivers

A GPS module is a device that uses Global Positioning System to determine the location of a vehicle or person. GPS receivers are used to

Emerging technologies are making our life simpler these days. With the introduction of mobile phones, life has changed rapidly. This is a dream of radio

FM Radio circuit is the simple circuit that can be tuned to the required frequency locally. This article describes the circuit of FM radio circuit.

We have already studied how to control the home appliances using RF communication in the post RF Remote Control Circuit for Home Appliances. Now let

There are different types of circuits that produce different kinds of sounds. Here is a simple circuit that produces wailing siren. The main principle of this

Audio tone control circuits are mainly used for 2 reasons. The first reason is to control the BANDWIDTH of the signal, which is entering into

CAUTION: Before going to explain about this concept, we are going to strictly suggesting that DON’T TRY TO IMPLEMENT IT PRACTICALLY AS IT PRODUCES VERY
