Know your basic formulas: V=IR, P=VI, P=I^2R, P=V^2/R Know the general characteristics of a digital signal Know X and Y axis on oscilloscope (time and voltage) Know the Nyquist sampling theorem Know high pass and low pass filters and how to explain how they work at the component level Know the difference between the DFT and FFT Know the X and Y axis of the FFT Know setup time and hold time Know the fourier transform of a sine wave and a square wave Look up jitter and s-parameters Know what db and dbm mean Know the difference between a digital signal at low speeds vs. high speeds (few Mhz vs few Ghz) Be able to look at a graph and determine period, frequency, and duty cycle Know the difference between a passive and active component For your basic questions, be sure you can list off two strengths and two weaknesses
