This infrared transmitter use PWM (pulse width modulation). The transmitter is equiped with LM567, tone decoder circuit. Audio signal ( at least 50mVvv ) is amplified with T1 and then it is used to ...

This project implements an IR signal transmitter and decoder using the TM4C123GXL (Tiva-C) microcontroller. It sends NEC protocol IR signals using a hand-soldered IR LED circuit and receives IR codes ...

As you might have noticed, the 38-KHz pulse generator is built around the evergreen timer chip NE555P (IC1). Here, the RC components (R5-C3-P1) set the astable frequency to drive the infrared light ...

If you are using infrared (IR) hardware in an IoT, embedded, or mobile hardware project and are currently experiencing difficulties debugging IR communications, using one of the circuits shown below ...

A new research project is aiming to establish whether germanium, a group IV semiconductor, can be used as the material of choice in mid-infrared (mid-IR) photonics circuits and sensors Mid-IR group IV ...

Abstract: Energy consumption evaluation for data processing tasks, such as encoding and decoding, is a critical consideration in designing very large scale integration (VLSI) circuits. Incorporating ...
