Abstract: A filter is described utilizing charge transfer devices for implementing transmission zeros. A first shift register is provided having a plurality of M stages, where M is an integer, each stage including a respective first charge storage region. A second shift register is provided having a plurality of N stages where N is an integer greater than M, each stage including a respective first charge storage region. A first sequence of packets of charge is provided, each packet representing a respective sample of an input signal. Each of the packets of charge of the sequence is divided into a first part and a second part equal to the first part. Each of the first parts of the packets of the first sequence is applied to the first shift register and transferred from stage to stage thereof at one frequency. Each of the second parts of the packets of the first sequence is applied to the second shift register and transferred from stage to stage thereof at the aforementioned one frequency. The product of the difference of the integers N and M and a predetermined frequency of the input signal for which zero transmission is desired is set equal to an odd integer multiple of one-half of the aforementioned one frequency.

Abstract: A charge transfer device having one or more control electrodes connected to switching means so that the electrode can perform two functions. Normally the electrode is used for charge transfer but it may be switched to act as a blocking electrode for blocking the charge present underneath it for one or more clock phases. This permits the device to be formed as a filter, an analog-to-digital converter or digital-to-analog converter in a simple and inexpensive manner. The charge transfer channel may be split into sections using isolation diffusions.

Abstract: A sampled data transversal filter utilizing charge transfer devices is described. The filter includes a charge transfer shift register including a plurality of stages to which a sequence of packets of charge representing samples of a signal is serially applied and clocked from stage to stage. Charge division and collection means are provided at the various stages of the shift register to divide and collect the fractions of charge appearing in the various stages thereof. These fractions represent the weighting coefficients of the various stages of the shift register. The charge collection means of the various stages are connected together to provide an output representing the sum of the charges collected at the various stages. The output sequence of packets of charge obtained represent the convolution of the input sequence of packets with the weighting coefficients of the various stages of the shift register.

Abstract: Apparatus for forming one or more sonar beams in response to acoustic energy received by a transducer array. To minimize volume utilization, a plurality of CCD's are formed on an integrated circuit chip with the CCD's being of progressively smaller length. Half of the CCD array is folded over to match the other half so that each CCD has an opposing CCD with both CCD's propagating a signal toward a common output diode. By providing one integrated circuit chip for each desired beam with appropriately different clocking frequencies multiple beams may be formed, and with the provision of a variable clocking frequency, one or more beams may be steered.Transversal filter operations may also be performed by the apparatus.

Abstract: The invention relates to an integrated filter circuit including a charge transfer device (CTD) transversal filter to which a sample-and-hold stage is post-connected. In such filters, a smoothing of the step-shaped signal output voltage emitted from the said stage is strived for. According to the invention, the smoothing ensues by means of a RC low pass which is realized by means of a "switched capacitor" circuit. This has two capacitors and two alternatively actuatable, electronic switches. The area of employment of the invention particularly embraces CTD transversal filters which are employed in systems with varying clock pulse frequencies.

Abstract: A comb filter comprising a charge transfer device (CTD) structure for separating frequency interleaved luminance and chrominance components of a composite color television signal directly within the CTD structure. The CTD structure has first and second pairs of input sections of substantially identical geometry, one input section of the second pair being preceded by a signal inverter. Signal charge as applied to the first and second input pairs are delayed such that signal charge from the first input pair exhibits a 1H delay relative to signal charge from the second input pair, when the signal charge from the respective input pairs are combined with each other. A first charge summing well combines mutually in-phase signal charge at multiples of the line scanning frequency from the first and second inputs to provide a combed luminance signal charge component, while a second well combines mutually inverted or out-of-phase signal charge at these frequencies from the first and second inputs to provide a combed chrominance signal charge component.

Abstract: In an illustrated embodiment, at least one analog shift register has a number of parallel inputs and one series output. A number of individual evaluating circuits receive the signal to be filtered and supply respective output quantities of charge equal to the product of the difference between the relevant signal value and a predetermined minimum or maximum value, and a respective individual evaluation factor. The output of each evaluating circuit can be connected via a switching element to an associated parallel input. According to the present teaching, a considerably lesser space requirement is realized by operating the filter so that for every consecutive scanned value of the signal each evaluating circuit is read in twice consecutively with a charge shift between such read-in processes, no charge shift being effected between the second read-in process and the first read-in process for the next scanned signal value. Read-in of the held signal may be effected more than twice.
