“…Early work describing the charge-pumped PLL and an analysis of the concomitant phase error was done by Gardner [Gardner 1980[Gardner , 1982. A subsequent attempt to produce a tunable, digital phase locked loop, implemented in discrete components, was reported from the University of Washington [Dahmani, 1981] [Caviglia, et al 1983]. must obtain in order that the loop filter dampening factor, s, be limited to a range of from 0.5 to 1.0, [Best, 1984].…”

In this paper the design of a single-board, microcomputer-controlled, digital pattern generator is discussed. The generator provides eight synchronous, TTL-compatible, NRZ channels. The controller is a 6s02-based Rockwell AIM 65 microcomputer. The generator master clock frequency is 10 MHz, but a single vector can be delayed from 100 ns to 99 000 s. Programmable delays avoid wasting memory in applications requiring short bursts of data followed by long steady-state conditions. Memory depth per channel is 100. The operational speed of the generator is independent of that of the controller. An interactive menu-driven program supports entry and editing of vectors for the sequence. After the sequence is transferred to the generator board the generator can be started/reset locally or by remote. The generator can be configured in the burst or continuous modes.Some attractive features of the design are simplicity of design, low cost, flexibility for expansion of the number of channels/memory deptp er channel, conversion into an arbitrary waveform generator, ap~h cation as a square-wave function generator from 5 JLHz to 5 MHz with programmable duty cycle, and seven supporting channels for trigger (with delay step of 100 ns or more). The generator has been applied in the characterization of nonvolatile semiconductor memory transistors which is an example of different delays between adjacent vectors by several orders of magnitude.

“…As a result of this time-discrete waveform generation however, signal harmonics are generated at integer multiples of the sample frequency plus or minus the signal frequency. For sinusoidal signals, their relative importance can easily be calculated [2] and is proportional to the ratio Fsignal I (Fsample -Fsignal). It turns out that, for a given signal-tonoise ratio, a good rule-of-thumb is to use the same number of bits for the address as for the data word size.…”

A flexible function generator with high-resolution programmability of frequency, amplitude, and dc offset has been developed for structural dynamics testing. The generator consists of a clock generator which defines the signal frequency and memory tables which define the signal functions. In order to obtain a fast-settling, stable, accurate variable clock signal, a frequency-locked-loop circuit was developed.
