摘要： To determine the period length of a first signal, the length is measured by counting the periods of a second signal with a shorter period length. To measure the fluctuations of the period length of the first signal whilst also taking into account the fluctuations of the period length of the second signal, the measurement is carried out for two different values of the period length of the second signal. Both the fluctuations of the period length of the first signal and the accumulated fluctuations of the period length of the second signal are calculated independently of one another from the two values. The method enables the period length fluctuations of a first signal that originates from a phase-locked loop to be detected.

摘要： In order to test the input and output drivers of a circuit, in particular an integrated semiconductor circuit, a method and apparatus is provided to connect the input or output drivers assigned to individual signal connections of the circuit to be tested in series to a ring oscillator or to an open chain with the oscillation of the ring oscillator or the delay time being evaluated. By providing appropriate controllable switches, the configuration of the ring oscillator or the chain can be altered variably depending on the input or output drivers to be tested respectively. In this way an “at-speed” and “leakage” test of all input and output drivers, including the external signal connections, are possible with all of these having to be connected to a rapid test unit.

摘要： A test apparatus for testing digitized test responses has a generator (2) and a signal extractor (3). The generator (2) uses direct digital synthesis to generate a set of n digital reference signals (xk, yk) which are orthogonal to one another. In this case, n is a natural number greater than 1. The signal extractor (3) contains a test input and a plurality of reference inputs. The test input receives a digitized test response (E) and the reference inputs are connected to the reference signals (xk, yk) which are generated by the generator (2). The signal extractor (3) generates scalar products from a respective reference signal (xk, yk) and the test response (E) and uses said products to calculate whether a combination of reference signals (xk, yk) is contained in the test response (E).
