The ESOLS Engineering product Audio Input section allows users to input audio signals from a microphone or an external source, such as a function generator. A gain control knob is provided to adjust the signal strength, ensuring flexibility in different experimental setups. The module also includes a low-pass filter to study noise reduction effects and improve signal clarity. This input audio signal can be utilized as a source for both Digital and Analog Communication Trainers, making it a versatile learning tool. The Audio Output section enables users to observe signals received from various demodulators, with a gain control knob for amplitude adjustment and an audio output jack for real-time monitoring through a headset.
