1972. This circuit modifies the pule repetition rate of initial and final pulses of a train by the product of inversely varying rate fractions controlled by a selected number of initial and final pulses of the train. The circuits disclosed in both of these applications are intended to optimize ...
Thesepulse generator circuits—a.k.a. an astable multivibrator oscillator circuit—employ a 555 timer IC, NE555 or LM555, in itsastable(free-running) mode. These types of circuits are often paired up with digital logic circuits. The 555 timer IC is also very popular and simple to use, with...
and a second complementary RC circuit coupled to an output of the first complementary RC circuit, wherein the first and second complementary RC circuits cooperate to produce an output signal based on the input signal, the output signal being delayed and having an adjusted pulse width with respect...
power supply supervisor circuits optimized for low-power microprocessor (µP), microcontroller (µC) and digital systems. They provide a reset output during power-up, power-down and brown-out conditions. They provide excellent reliability by eliminating external components and adjustments. ...

III Pulse and Digital Modulation In cw modulation, some parameter of a sinusoidal carrier wave is varied continuously in accordance with the message. This is in direct contrast to pulse modulation, in which some parameter of a pulse train is varied in accordance with the message. There are two...
For these circuits, the output duty cycle is a function of the amplitude of the triangle wave (VTRI) and amplitude of the input signal (VIN). The average output voltage (VO) depends on the amplitude of the PWM waveform (VPWM) which is typically determined by the supply voltages of the ...
To break things down further,PWM circuits[PDF] typically involve a very tiny power source, and a large one. The tiny power source controls the large one with the help ofpowertransistors. The tiny one generates thesignal, and the ‘power‘ which is the large current and voltage that actually...
