摘要： An electronic filter operates as a correlator that provides a discrete approximation of an analog signal. The analog to digital conversion is integrated directly approximation calculation. An array of sample and hold circuits or single bit comparators provide outputs to a series of multipliers, the other input of which is a coefficient value of a Fourier series approximation of the desired frequency response. Each of the sample and hold circuits samples sequentially in time and holds its sample until the next cycle. Thus the sample point rotates in time through the array and each new sample is multiplied by a different coefficient. The output of the multipliers is summed for evaluation.

摘要： A method of convoluting a first signal (32) and a second signal. The method includes generating a multiplication signal responsive to the second signal, multiplying (34) the first signal by a plurality of time shifted versions of the multiplication signal, integrating (38) the products of the multiplying of the first signal and the plurality of time shifted versions of the multiplication signal, the integrations being performed over a time period longer than the time difference between at least two of the time shifted versions, and providing an output signal based on the integrations of the products.

摘要： A first and a second MOS transistor of the same conductivity type are connected in series between a load and a fixed voltage source. The gates of the first and second MOS transistors are connected to sources of input voltage which are of a magnitude smaller than the threshold voltages of the two MOS transistors. The first MOS transistor located next to the load is kept in saturation. A related circuit includes a first and a second MOS transistor of the same conductivity type are connected in series between a load and a fixed voltage source. The first MOS transistor located next to the load is kept in saturation. The gates of the first and second MOS transistors are connected to the gates of third and fourth diode-connected MOS transistors of the same conductivity type as the first and second MOS transistors. The third MOS transistor is connected between a first input current node and a fixed voltage source. The fourth MOS transistor is connected between a second input current node and a fixed voltage source. The third and fourth MOS transistors may alternatively be connected to first and second input transistors and a bias transistor arranged as in a differential amplifier. At least one diode-connected transistor is included in series with at least one of the transistors which has a gate connected to an input voltage.

摘要： Disclosed are two modifications of the Tank-Hopfield circuit, each of which enables the deconvolution of a signal in the presence of noise. In each embodiment, the Tank-Hopfield circuit is modified so that the equation for total circuit energy reduces to one term representing convolution and another information theoretic (or Shannon) entropy. Thus, in finding its global minimum energy state, each modified circuit inherently identifies an optimal estimate of a deconvoluted input signal without noise.

摘要： A device which provides bidimensional correlation of an image obtained by the scanning of electromagnetic or acoustic waves of the reference image. The scanned image and the reference image are written into memories with a pair of memories storing the real and imaginary portion of the signal of the corresponding images. After analog conversion, the signals are placed on a carrier and correlated in a line-by-line manner through the use and elastic wave convolver. The output of the convolver is demodulated with a correlation signal being applied to an adder and the correlation image being stored with its real and imaginary portions in a set of memories to provide a bidimensional correlation of an image.

The functions X(t) and Y(t) are applied to the two inputs of the ambiguity meter. The signs Z1 and Z2 are detected, then sampled by AND-gates. sgn Z2(t-r) is stored in a shift register and integration is performed in the stages of a Fourier transformation circuit.
