Patent JP-H05276041-A (JP)
Title: Pulse analyzer
IPC: H03M3/00
Filed: 1992-03-30
Abstract: PURPOSE:To reduce the conversion time while keeping a frequency of a clock pulse and conversion resolution constant by counting the clock pulse at a prescribed rate till a pulse level of an input signal reaches a zero level from a maximum level. CONSTITUTION:A 1st conversion means (counter) 3 counts main clock pulses CS for a falling time from a maximum level to a zero level. Then a pulse level at a maximum level of an input signal based on the count is converted into an n-bit digital signal. On the other hand, when the input signal is at a zero level, a 2nd conversion means (discrimination circuit) 5 discriminates a level of a main clock pulse CS to convert the signal into a 1-bit digital signal. The 1-bit digital signal from the circuit 5 is added to a low-order of the n-bit digital signal outputted from the means 3 and the result is stored in a memory 6 as the result of analysis of a pulse level in (n+1) bits. Thus, the conversion time is halved and the conversion resolution is doubled without increasing the frequency of the main pulse CS.
