LECTURE #1 THE OSCILLOSCOPE/THE SPECTRUM ANALYZER THE OSCILLOSCOPE [O-SCOPE] 1. What are oscilloscopes used for? to display voltage waveforms in the time-domain 2. Oscilloscopes allow us to perform time-domain measurements such as wave-shape, phase-shifting, frequency, and period. 3. V p = peak voltage V p-p = peak-to-peak voltage V rms = V eff = RMS or Effective Voltage V avg = Average Voltage

Time is on the x-axis. Voltage is on the y-axis. V(t) = V p sin (ωt + θ) V rms = 0.707 × V p V avg = 0.636 × V p ω = angular frequency in units of (rad/s) t = time in seconds (s) V(t) = instantaneous voltage signal ω = 2πf T 1 f = f 1 T = f is the symbol for electrical frequency in units of Hertz. The frequency is defined as the number of times the wave changes direction in one second. Frequency can also be defined as the number of cycles in one second. T is the symbol for the period in units of seconds (s). The period is defined as the amount of time it takes a waveform to repeat itself. The period can be assigned as the amount of
