Steps involved in A/D conversion

• Sampling: The continuous analog signal is sampled at regular intervals.

• Quantization: Each sample is assigned a digital value based on its amplitude.

• Encoding: The digital values are encoded into binary format for processing.

• Resolution: The number of bits used to represent each sample determines the resolution.

• Conversion: The final step involves converting the digital signal into an analog output.

Types of digital filters include FIR filters, IIR filters, and adaptive filters.

• FIR filters: Finite Impulse Response filters have a finite impulse response, meaning they only respond to a finite duration input signal.

• IIR filters: Infinite Impulse Response filters have an infinite impulse response, allowing for feedback in the filter design.

• Adaptive filters: These filters adjust their parameters based on the input signal, making them suitable for changing environments.

• Examples...read more
