Simplified system displays complex curves corresponding to input data
Cathode ray oscilloscope displays curves or contours of complex shapes corresponding to sets of x,y coordinates. It requires few storage facilities and produces a rapid display of complex curves with a fewer number of commands than previous systems.

Digital input is buffered to real-time analog display
Buffering technique utilizes nine-bit binary counter and holding register of eight flip-flops. These flip-flops form the memory device that allows precise asynchronous conversion of the digital source data. Counter generates a waveform which is passed through a low pass filter to recover data in analog form.

Dual-channel circuit conditions/amplifies transducers' inputs and outputs
Circuit includes two data channels and one shared precision power supply installed on a single 11.4 cm square circuit card. The unit is relatively inexpensive, compact, and suitable for most tests where low-noise and high-gain signal processing is required.

Approximate properties of the response of nonlinear dynamic systems to stochastic inputs
Indirect method considers effect of nonlinearity and obtains approximate probability densities of certain characteristics, from these densities various statistical properties are calculated. Direct method determines response moments directly. Neither method is restricted by system motion with regard to whether or not it is stationary.
