Chapter 17: Fundamentals of Time and Frequency

pulse width and polarity varies from device to device, but TTL levels are commonly used. The test signal for frequency measurements is usually at a frequency of 1 MHz or higher, with 5 or 10 MHz being common. Frequency signals are usually sine waves, but can also be pulses or square waves. If the frequency

accurately (within 2%) show the amplitudes of sine-wave signals up to 20 MHz. For digital signals, oscilloscopes must capture the fundamental, third and fifth harmonics or the display will lose key features. So, the bandwidth of the scope together with the probe should similarly be at least 5x the maximum signal

TECHNICAL NOTE Overview of IRIG-B Time Code Standard

IRIG-B is typically distributed as a DC level shift (DCLS), pulse-width coded signal ( unmodulated IRIG-B ) or as an amplitude-modulated signal based on a sine wave carrier with a frequency of 1kHz ( modulated IRIG-B ). Modified Manchester modula-tion is also specified in the standard but is less common. A comparison of IRIG-B

Fig.2 definition of Rise Time (tr) For example, for a rise in voltage between 0.1x U peak and 0.9x Upeak of 500Volts over a rise time of 250ns (0.25µs) equates to a dV/dt of 2000V/µs. Whilst there is some paranoia over dV/dt levels, if the motor used meets the relevant IEC standards, dV/dt rarely causes an issue (see below).

CHAPTER 2 SINGLE PHASE PULSE WIDTH MODULATED INVERTERS

The comparator output is processesed in a trigger pulse generator in such a manner that the output voltage wave of the inverter has a pulse width in agreement with the comparator output pulse width. The magnitude ratio of c r v v is called the modulation index and it controls the harmonic content of the output voltage waveform.

either positive or negative. It may be a sine wave or other analog function, a digital pulse, a binary pattern, or a purely arbitrary wave shape. The signal source can provide ideal waveforms or it may add known, repeatable amounts and types of distortion (or errors) to the signal it deliv-ers. See Figure 2.

So if θ2 −θ1 >90°, then the actual inverse sine is [180°−sin−1()C / A], where sin-1 represents the principle inverse sine between 0° and 90°. Second, what is the sign of ()θ2 −θ1?

Improving FFT Frequency Resolution

FFT size. For example, an FFT of size 256 of a signal sampled at 8000Hz will have a frequency resolution of 31.25Hz. If the signal is a sine wave of 110 Hz, the ideal FFT would show a sharp peak at 110Hz. Unfortunately, with the given frequency resolution, the energy will be split between bins 4 and 5 (93.75Hz and 125Hz, respectively).

Pulse Width Modulation Control (PWM) The H Bridge Gates G1-G4 are fed by the combined signals from the Sine and Triangle Wave generators The sine wave will be at 50/60Hz and the Triangle wave at the Chopping or Carrier frequency (5kHz -100kHz). This produces the variable mark space pulse output in phase with the controlling Sine Wave.

For a general real function, the Fourier transform will have both real and imaginary parts.

Pulse duation is related to duty cycle, the percentage of time that pulses are on, relative to total time on and off; for example, if pulse duration is increased while pulse frequency remains constant, duty
