Stereo Audio Pre-Amplifier Circuit with Bass and Treble Control using Transistors Often times, we need to control bass, treble, and volume of our audio signal before passing it through amplification stages to prevent sound distortion. The circuit that amplifies the audio signal before it enters the main speaker amplifier is called an Audio Preamplifier. The use of an audio pre-amplifier ensures good audio quality and provides options to modify our sound… |

Build Your Own Guitar Distortion Pedal Circuit Who does not like the rumbling tone of a distorted electric guitar? It is a key part of many important genres of music, especially in blues and rock music genres and is also frequently used in hard rock, metal or the punk music genre. In this project, we will build a basic distortion pedal for guitars using a simple circuit. You can also check out the Arduino Guitar Tuner Circuit if you are… |

Superheterodyne AM Receiver - Working with Block Diagram and Schematics A superheterodyne receiver uses signal mixing to convert the input radio signal into a steady intermediate frequency (IF) that can be worked with more easily than the original radio signal, which has a different frequency, depending on the broadcasting station. The IF signal is then amplified by a strip of IF amplifiers and then fed into a detector that outputs the audio… |

IoT Based Smart Reminder System Have you ever set an important reminder on your phone only to miss it because the device was in silent mode, left in another room, or buried under tons of notifications? While smartphones have made reminders convenient, they are not always used in every situation, especially for elderly people, students, or professionals with busy schedules.To solve this problem, we… |

Arduino Based FM Radio using RDA5807 Today almost everyone uses their mobile phones to listen to music, news, podcasts, etc. But not long ago we were all depending on local FM Radios to get the latest news and songs, slowly these Radios are losing popularity but in emergencies when the internet is down, radios place an important role to transmit information to the users. Radio signals are always present in the… |

12V Audio Power Amplifier using TIP35C – Class A Amplifier Loudspeakers are heavy loads, and they normally require high current to be driven which is provided by an external circuit. This is because sometimes the produced sound output, let's say from a microphone or the pickup coils of the guitar, do not produce high current high amplitude output, therefore, it is not suitable to drive a loudspeaker. This is why we have something… |

Pi Filter - Overview, Working, Construction, Application and Design Tips Filters are commonly used in power and audio electronics to reject unwanted frequencies. There are many different types of filters used in electronic circuit designs based on the application but the underlying concept of all of them is the same, that is to remove unwanted signals. All these filters can be categorized into two types- Active filters and passive filters. The… |

How to build an Analog Mixer - Additive Mixer and Multiplicative Mixer A mixer is a special type of electronic circuit that combines two signals (periodically repeating waveforms). Mixers find a lot of use in audio and RF systems and rarely used as simple analog ‘computers’. There are two types of Analog Audio Mixers - Additive Mixers and Multiplicative Mixers. 1. Additive Mixers Like their name suggests, additive mixers simply add… |
