Abstract

In this paper, some circuits for digital modulation applications circuits are performed using an IC and few components on project board. For generation of these circuits for digital communication modulation application experiments, various costly, heavy-weighted and tedious circuits and devices have been discovered and are available. This paper presents a very economic, light-weighted and simple circuits, those uses one or two LF 398 IC, LM 741 IC and a single resistor and/ or capacitor for generation of PAM, natural sampling, flat-top sampling, sample and hold, PAM-TDM, PWM, ASK, FSK & PSK modulation against conventional transistor based methods. Tested hardware circuits and their resultant observed waveforms have been included that justify behavior of the hardware circuitry. Laboratory implementation of digital modulation applications have been presented in this work.
