We present the power spectrum of a sinusoidal carrier, frequency modulated by a random baseband pulse train in which the signaling-pulse duration is finite and the signal pulses may overlap and have different shapes. Symbols transmitted during different time slots are assumed to be statistically inde...
The diode junction DJ1 forms part of a transistor in a multivibrator. The timing signal comprises pulses substantially coincident with minimum amplitude peaks of the sinusoidal waveform VC. The pulses correspond to conduction of the diode junction. 展开 ...
A square signal of 50 Hz is adopted in the utility model to be output to track the commercial power; besides, a square wave of 38.4 KHz is also output to ensure a more accurate tracking of the commercial power for the UPS; specially, simultaneous tracking of a plurality of UPSs ensures...
The root-mean-square value of this direct current can reach the peak value of the sinusoidal current depending on the phase relation.The output current in this state is greater than the rated current IN by a factor of √2. The individual motor terminals and cables are designed thermically ...
