Abstract
A programmable digital pulser for pulsed NMR applications employing inexpensive integrated circuits is described. This pulser employs two types of modules, one master clock and several counters. The required pulse sequence determines the number of counters to be front‐panel interconnected. The master clock module simultaneously provides crystal‐controlled clock pulses with periods from 10−7 to 1 sec in decade steps. These pulses are used by the counter modules to generate either time delays or pulses with a maximum resolution of five digits.Keywords
