چکیده
Abstract: Electromagnetic interference (EMI) has a negative effect upon the performance of circuit communication systems. The present study considers the case of EMI and it is shown that the harmonic noise increases with an increasing interference amplitude and frequency. When electromagnetic interference takes place with the input pins of 555 Timer using as an Monostable Multivibrator it can cause operation variation. This paper deals with the investigation of EMI effects in 555 timer circuit. This work presents evaluation of the EMI effects in 555 timer by applying a range of EMI signals varying from 5MHz-30MHz at constant magnitude of 100mV in series along with the 5Hz/5V original input signal. The EMI effects on the test 555 timer are predicted using ORCAD in terms of total job time, time step and output waveform. All the results compiled in the paper are simulated from the same. For easier understanding Bar graph is shown.

Jitter Effects in Continuous - Time Modulators Withdelayed Return - to - Zero Feedbacko
A general method to design continuous-time Sigma{ Delta ((() modulators with delayed return-to-zero (RZ) feedback pulse is presented. This method can be applied to design modulators with any arbitrary delay and pulse width. It is shown that the key-point to avoid the degrading eeects of clock jitters, is to generate a low jitter feedback pulse-width, using a monostable multivibrator.

متن کاملFrom circuits to spectral peaks
A class of clockedlautonomous circuits is defined in which the behaviour is described by a one-dimensional mapping. For these circuits, the power density spectrum at the harmonics of the clock frequency can be calculated directly from the invariant density of the mapping. An algorithm for carrying out this calculation is derived and illustrated, using the clocked monostable multivibrator as an ...

This short note is to fix the gap for the proof of Lemma 3.8 in our previous paper [M. Mei, C. Ou and X.-Q. Zhao, SIAM J. Math. Anal., 42 (2010) 2762-2790].
متن کاملAdmissible speeds of transition fronts for nonautonomous monostable equations
We consider a reaction-diffusion equation with a nonlinear term of the Fisher-KPP type, depending on time t and admitting two limits as t → ±∞. We derive the set of admissible asymptotic past and future speeds of transition fronts for such equation. We further show that any transition front which is non-critical as t → −∞ always admits two asymptotic past and future speeds. We finally describe ...
