Bark frequency transform using an arbitrary order allpass filter 1
We propose an arbitrary order stable allpass filter structure for frequency transformation from Hertz to Bark scale. According to the proposed filter structure, the first order allpass filter is causal, but the second and higher order allpass filters are non-causal. We find that the accuracy of the transformation significantly improves when a second or higher order allpass filter is designed co...
متن کاملAllpass IIR filter
For every implementation we will take a look at the following characteristics: the ratio between the sample rate and processing rate (K), number of simultaneous inputs (P ), required hardware, hardware utilization, multiplications per output sample, cycle time, throughput, response time, latency and the number of locations that have to be updated when the filter coefficients change. A summary o...
متن کاملRC Allpass Delay Filter
This technical report presents the development of a simple envelope, or group, delay filter whose magnitude response emulates allpass characteristics for relatively broad frequency passbands. Unlike traditional allpass delay networks, the filter presented herewith exploits no inductances and maintains a common ground between its input and output ports. The absence of circuit inductances simplif...
متن کاملSpectral Distortion Using Second-Order Allpass Filters
This work presents a technique for detuning or applying phase distortion to specific spectral components of an arbitrary signal using a cascade of parametric second-order allpass filters. The parametric second-order allpass provides control over the position and slope of the transition region of the phase response, and this control can be used to tune a phase distortion effect to a specific fre...
متن کاملAllpass filter design and applications
The problem of allpass lter design for phase approximation and equalization in the Chebyshev sense is solved by using a generalized Remez algorithm. Convergence to the unique optimum is guaranteed and is achieved rapidly in the actual implementation. The well-known numerical problems for higher degree lters are analyzed and solved by a simple approach. Possible applications are: design of lters...
