Digital Filters Design topics include: The design of low pass butterworth filters and chebyshev filters, bilinear transformations, filter coefficient quantization, design considerations for filters, FIR filter design using windows, forward and backward difference methods, filter design using frequency sampling method, FIR differentiator design, Hilbert transformer design, IIR filter design, approximation of derivatives, impulse variance, analog filter characteristics, various approximation methods, sampling rate conversion and interpolation techniques.
Digital filter design involves using both frequency domain and time domain techniques. The filter specifications are often specified in the frequency domain and the implementation is done in time-domain in the form of difference equations.
The steps in digital filter design are: Determine specifications Find a transfer function Choose a realization structure Implement the filter
The two fundamental types of digital filters are finite impulse response (FIR) and infinite impulse response (IIR).
A digital filter is a mathematical algorithm implemented in hardware and/or software that operates on a digital input signal to produce a digital output signal. Digital filters have the following advantages: They require only the arithmetic operations of addition, subtraction, and multiplication They do not drift with temperature or humidity or require precision components They have a superior performance-to-cost ratio They do not suffer from manufacturing variations or aging
