Measurements about the frequency and time domain characteristics of two “multi-rate” filter banks: a pure DFT, realized by an FFT processor, and a combination of a special polyphase network with the FFT are reported on. The theoretical comparison and the hardware of both systems were described in a previous paper [1]; this contribution details the measuring arrangement and equipment. Applications are demonstrated, using not only well defined test sequences, but also “real world” signals. Modifications, necessary for possible ameliorations or other applications, are addressed. 相似文献

In many of the applications envisioned for organic thin-film transistors (TFTs), the electrical power will be supplied by small batteries or energy harvesters, which implies that it will be beneficial if the TFTs can be operated with voltages of 1 V or even below 1 V. At the same time, the TFTs should have large on/off current ratios, especially for applications in digital circuits and active matrices. Here we demonstrate p-channel and n-channel organic TFTs fabricated on a flexible plastic substrate that have a turn-on voltage of exactly 0 V, a subthreshold slope of 100 mV/decade, and an on/off current ratio of 2 × 105 when operated with gate-source voltages between 0 and 0.7 V. Complementary inverters fabricated using these TFTs have a small-signal gain of 90 and a minimum noise margin of 79% at a supply voltage of 0.7 V. Complementary ring oscillators can be operated with supply voltages as small as 0.4 V. 相似文献

The design of a digitally-tunable sixth-order reconfigurable OTA-C filter in a 0.18-μ m RFCMOS process is proposed. The filter can be configured as a complex band pass filter or two real low pass filters. An improved digital automatic frequency tuning scheme based on the voltage controlled oscillator technique is adopted to compensate for process variations. An extended tuning range (above 8:1) is obtained by using widely continuously tunable transconductors based on digital techniques. In the complex band pass mode, the bandwidth can be tuned from 3 to 24 MHz and the center frequency from 3 to 16 MHz. 相似文献

An approach to implement wave digital filter is presented. The implementation method is applicable to wave digital filters containing only 3-ports adaptors, connected with reflection-free ports. All arithmetic operations are performed in a special arithmetic unit. Main features are the fact that the arithmetic units are effectively utilized, and that only a few memories of standard type are needed. 相似文献
