Efficient Digital Filters with Variable Cut-off Based on All-pass and Sharpening Digital Filters
All-pass digital filters are known as excellent prototype filters in many applications, such as control systems, signal processing and communications. Efficient filters can be designed because transfer function is very robust to small element changes. The drawback of digital filters based on all-pass filter sections is that they are not suitable for tuning and the design of filters with variabl...

متن کاملFast Adaptive Detection of Sinusoidal Signals Using Variable Digital Filters and All-pass Filters
This paper proposes an adaptive line enhancer (ALE) using a variable band-pass (BP) filter and an all-pass filter. The proposed ALE has the high convergence speed and the small steady-state value of the squared error. The all-pass filter outputs the signal which consists of a sinusoidal signal which has the same phase as that of the input signal to the ALE and a white noise which has no correla...
متن کاملIntegrated Design of IIR Variable Fractional Delay Digital Filters with Variable and Fixed Denominators
In this chapter, the following abbreviations are used: Variable-denominator IIR VFD filters as VdIIR VFD filters. Fixed-denominator IIR VFD filters as FdIIR VFD filters. Allpass VFD filters as AP VFD filters. FIR VFD filters the same as FIR VFD filters. Symbol t is used to represent fractional delay (instead of the symbol d normally used to denote the operation of differentiation). Five frequen...
متن کاملDigital Filters
You will be able to: • Implement a digital filter in MATLAB. • Investigate how commercial filters work • Describe the transfer function of a filter Suppose the "raw" signal which is to be digitally filtered is in the form of a voltage waveform described by the function V = x (t) where t is time. This signal is sampled at time intervals h (the sampling interval). The sampled value at time t = ih...
