New Gain Controllable Resistor-less Current-mode First Order Allpass Filter and its Application
New first order allpass filter (APF) in current mode, constructed from 2 CCCCTAs and grounded capacitor, is presented. The current gain and phase shift can be electronically /orthogonally controlled. Low input and high output impedances are achieved which make the circuit to be easily cascaded to the current-mode circuit without additional current buffers. The operation of the proposed filter h...
متن کاملBark 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 کاملResistorless voltage-mode first-order allpass section using single current- controlled conveyor transconductance amplifier
This paper presents an alternative configuration for realizing a canonical voltage-mode first-order allpass (AP) section with electronic tuning. The proposed circuit is composed of only one CCCTA and one floating capacitor, which results in a simple and resistorless structure. Its phase response can be adjusted electronically through the external dc bias currents of the CCCTA. Simulation result...
