Drag onto the page to add a pulse width modulator.
The transmitter has a level separator for separating the envelope signal into a signal in a first envelope signal section not more than a reference level and a signal in a second envelope signal section not less than the reference level according to the signal level of the envelope signal, a pulse width modulator for performing the pulse width modulation of the envelope signal in the first envelope signal section, an amplifier for linearly amplifying the envelope signal in the second envelope signal section, a transistor for performing a switching operation according to a pulse width modulation signal to amplify the pulse width modulation signal, and a smoothing circuit for smoothing the combined signal of an output signal of the amplifier and an output signal of the transistor or an output signal of the transistor before the combination, which is supplied to the power supply terminal of the power amplifier.
For example, switched-mode power supplies and induction motor-control circuits often use a triangular wave oscillator as part of the pulse width modulator (PWM) circuit.
A radiation detector (1) includes a pulse width modulator (11) which binarizes the analog electrical pulse P output from a detection cell (7) using a specified threshold Vth for modulation into the digital electrical pulse Pp, and a data superimposition unit (13) which outputs the radiation incoming position pulse train Pt by superimposing the radiation incoming position pulses Px and Py relative to a radiation incoming position on the detection cell (7) and the digital electrical pulse Pp detected by the radiation, thereby allowing the positional information which has been conventionally added behind the output of the digital electrical pulse Pp to be added into the digital electrical pulse Pp.
According to the PWM signal Vpwm outputted from the pulse width modulator (60), a logic controller (70) controls switching of current of the primary side coil of the transformer.
A pulse width modulator (60) generates a PWM signal Vpwm whose duty ratio is feedback-controlled so that a detection voltage Vdet based on current of the secondary side coil of a transformer approaches a reference voltage Vref.
The transmitter has a level separator for separating an envelope signal into a signal not less than a reference level and a signal less than the reference level according to the signal level of the envelope signal, a first pulse width modulator for performing the pulse width modulation of the signal not less than the reference level to form a first pulse width modulation signal, a second pulse width modulator for performing the pulse width modulation of the signal less than the reference level to form a second pulse width modulation signal, a first transistor to which a first applied voltage is supplied and which allows the first pulse width modulation signal to switch over the first applied voltage for output, a second transistor to which a second applied voltage smaller than the first applied voltage is supplied and which allows the second pulse width modulation signal to switch over the second applied voltage for output, and a smoothing circuit for smoothing the combined signal of the output signals of the first and second transistors to output it to the power supply terminal of a power amplifier.
This function automatically transfers data in the register of each module to other modules, enabling automatic transfer of data from an A/D converter to a digital signal processor (DSP) and from the DSP to a pulse width modulator (PWM), for instance.
