DSP based is unit 2 12m and it has been repeated in both sets For unit 3, I have taken one question from each set 12M: Mention briefly about the DSP Based hearing aids with a neat block diagrams Since the introduction of the first commercial digital hearing aid in 1996, the possibilities of Digital Signal Processing (DSP) have increasingly been exploited in hearing aids DSP allows for the implementation of signal processing schemes that have no counterpart in the analog domain Binaural hearing aid: Hearing: Hearing is considered as the most important senses of humans because it connects us to the world. So hearing loss can have a significant effect on our life, from our work to our connections and enthusiastic prosperity. A hearing aid is an electro-acoustic gadget, which is intended to increase sound, with the point of making speech more comprehensible. The fundamental task of the hearing aid is to selectively amplify sound signals to such an extent that the handled s...
4M: Compare and contrast different Neural Network Architecture Feedforward NN Feedback NN Self-organizing NN Layers of neurons connected in a forward direction without cycles Layers can form cycles, allowing feedback loops Neurons are organized into a lattice structure Simplicity, ease of implementation Capturing temporal dependencies, dynamic behavior Adaptive learning, ability to detect patterns Suitable for structured data Suitable for temporal or sequential data Suitable for clustering and unsupervised learning Cannot capture temporal dependencies Complexity in training, potential instability Lack of supervised training, interpretability challenges Regression, classification tasks Time-series prediction, dynamic systems Pattern recognition, data visualization Compare and contrast forward propagation and backward propagation Forward propagation Backward propagation Calculate the output of the neural network Adjust weights to minimize the error Input data is passed through the ...
