Abstract: Room acoustics simulation is achieved by digitally defining delay and weighting parameters and generating sampled analog signal responses. In the early portion of a response term an accurate impulse response is provided and subsequently high echo density is simulated using sampled analog signal Schroeder sections. A sampled data analog signal device is used which employs charge transfer devices as programmable delay media, multiplying digital to analog converters to generate weighting of the analog signal and a general purpose microprocessor as a parameter calculator. The early impulse response characteristic is accomplished by providing a time domain finite impulse response (FIR) section in a transversal filter arrangement which directly feeds to an ultimate output and to parallel comb filter sections which in turn input to at least one all pass section of the so-called Schroeder configuration. The charge transfer devices are employed as programmable delays to propagate the analog signals. All weighting coefficient products are generated by multiplying digital-to-analog converters.

Abstract: A filter utilizing charge transfer devices for providing recursive transfer functions with a transmission zero at d.c. or zero frequency is described. The filter includes a circular charge transfer shift register having an even number N of stages, greater than two, and first, second, third and fourth linear charge transfer shift registers. All five shift registers are clocked at the same frequency. A first input sequence of packets of charge representing positive weight components of a signal, and a second sequence of packets of charge representing negative weight components of the signal are provided. Means are provided for dividing each of the packets of charge of the first input sequence into a first part and a second part and for applying each of the first parts of the packets of the first input sequence to the input stage of the first shift register and for applying each of the second parts of the packets of the first input sequence to the input stage of the second shift register. The charge packet in the first charge storage cell in the K.sup.th stage of the first shift register is combined with the charge packet in the first charge storage cell of the N.sup.th stage of the circular shift register. The combined packet of charge is divided into two portions, a first portion being stored in the first charge storage cell of the K.sup.th stage of the first shift register from which it is clocked out and sensed and a second portion being stored in the first charge storage cell of the N.sup.th stage of the circular shift register. The charge packet in the first charge storage cell of the L.sup.th stage of the second shift register is combined with the charge packet in the M.sup.th stage of the circular shift register, where M is an integer less than N/2 and L=K+M.Means are provided for dividing each of the packets of charge of the second input sequence into a first part and a second part and for applying each of the first parts of the packets of the second input sequence to the input stage of the third shift register and for applying each of the second parts of the packets of the second input sequence to the input stage of the fourth shift register. The charge packet in the first charge storage cell in the K.sup.th stage of the third shift register is combined with the charge packet in the first charge storage cell of the (N/2).sup.th stage of the circular shift register. The combined packet of charge is divided into two portions, a first portion being stored in the first charge storage cell of the K.sup.th stage of the third shift register from which it is clocked out and sensed and a second portion being stored in the first charge storage cell of the (N/2).sup.th stage of the circular shift register. The charge packet in the first charge storage cell of the L.sup.th stage of the fourth shift register is combined with the charge packet in the (N/2+M).sup.th stage of the circular shift register.A first output sequence of packets of charge representing the positive components of an output signal is obtained at the output of the first shift register. A second output sequence of packets of charge representing the negative components of the output signal is obtained at the output of the second shift register. The output signal is obtained by differentially summing corresponding charge packets in the first and second output sequences.

Abstract: Disclosed is a charge transfer device, like a transversal filter, having means for detecting if an amount of signal charge transferred from one stage to another falls within a dynamic range of the device. A charge transfer channel is so formed as to have first and second branched output ports. A signal charge transferred to the first output port is detected as an output signal supplied to a utilization circuit while an output voltage caused by a signal charge transferred to the second output port is compared with first and second reference voltages which correspond to first and second amounts of signal charges substantially determining upper and lower limits of the dynamic range of the device, whereby it is detected if the amount of the signal charge transferred is within the dynamic range or not. As a result of the detection when the signal charge amount is outside the dynamic range, the supply of the output signal to the utilization circuit is interrupted.
