rectangular pulse造句

With a 50 % duty cycle each rectangular pulse is only at a positive voltage for half of the bit period.
Pulse-width modulation uses a rectangular pulse wave whose pulse width is modulated resulting in the variation of the average value of the waveform.
The'professional'grade accepts only CSW files, which represent waves preprocessed into rectangular pulse trains, but it encodes all audio information supported by the UEF specification.
A good transient response is necessary to maintain the rectangular pulse shape at the secondary, because a pulse with slow edges would create switching losses in the power semiconductors.
The effects of filtering a rectangular pulse not only change the shape of the pulse within the first symbol period, but it is also spread out over the subsequent symbol periods.
It's difficult to find rectangular pulse in a sentence. 用rectangular pulse造句挺难的

By charging the transmission line and then discharging it into a resistive load, a rectangular pulse equal in length to twice the electrical length of the line can be obtained, although with half the voltage.
:For me, I interpret s ( t ) as being a windowed function, so it would be the function s ( t ), times a rectangular pulse which goes from-1 to 1.
The simple moving average corresponds to convolution with the constant B-spline ( a rectangular pulse ), and, for example, four iterations of a moving average yields a cubic B-spline as filter window which approximates the Gaussian quite well.
For example, a low-complexity scheme referred to as WCP-OFDM ( ) consists of using short filters at the transmitter output in order to perform a potentially non-rectangular pulse shaping and a near perfect reconstruction using a single-tap per subcarrier equalization.
In a binary direct-sequence system, each chip is typically a rectangular pulse of + 1 or 1 amplitude, which is multiplied by a data sequence ( similarly + 1 or 1 representing the message bits ) and by a carrier waveform to make the transmitted signal.
