Pspice simulation of an electro-acoustic communications channel

PSpice for Analog Communications Engineering

In PSpice for Analog Communications Engineering we simulate the difficult principles of analog modulation using the superb free simulation software Cadence Orcad PSpice V10.5. While use is made of analog behavioral model parts (ABM), we use actual circuitry in most of the simulation circuits. For example, we use the 4-quadrant multiplier IC AD633 as a modulator and import real speech as the mod...

PSpice for Digital Communications Engineering

PSpice for Digital Communications Engineering shows how to simulate digital communication systems and modulation methods using the very powerful Cadence Orcad PSpice version 10.5 suite of software programs. Fourier series and Fourier transform are applied to signals to set the ground work for the modulation techniques introduced in later chapters. Various baseband signals, including duo-binary ...

Temperature Independence of an Electro Acoustic Capnograph

End tidal carbon dioxide measurement with an electro acoustic sensor has recently been demonstrated. The sensor consists of an acoustic resonator coupled to a low cost electro acoustic element. The aim of this study was to verify if ambient temperature variation would affect the measurements. By simultaneous measurements with a reference sensor, the electro acoustic capnograph was tested on sub...

Pspice Simulation of Power Electronics Circuit And

This paper shows how power electronics circuits, electric motors and drives, can be simulated with modern simulation programs. The focus will be on PSpice, which is one of the most widely used general-purpose simulation programs. A simulation example is presented, and the results are compared with those obtained with Power System Simulation Tool based on Simulink.
