This paper delves into the key modulation techniques and demonstrates their simulation using LabVIEW, providing valuable ...

let’s create a waveform simulating an ultrasonic range finder operating at 40 kHz. The range finder transmits a 40-kHz sinewave carrier amplitude modulated by a Lorentzian pulse. This is followed by a ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

A proposed Extensible SOQPSK modulation waveform brings the best of both OFDM modulation and single-carrier SOQPSK modulation to telemetry applications. Since the introduction of multi-carrier (MC ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

Since they are exact opposites of each other, if they are represented as a single modulated waveform in a single channel, they cancel each other out. Understanding why waveforms are measured by ...

A new chip-scale laser from Rochester and UCSB enables ultra-fast, precise measurements for uses such as LiDAR.
