ecor 1043 terms special case two resistors in parallel - CORRECT ANSWER-i1 = R2 / (R1 + R2) x i, i2 = R1 / (R1 + R2) x i special case two resistors in series - CORRECT ANSWER-v1 = R1 / (R1 + R2) x v, v2 = R2 / (R1 + R2) x v Transfer function - CORRECT ANSWER-ratio of output (response) to the input (source) of a circuit Passband - CORRECT ANSWER-o the range of frequencies that are allowed to pass through the filter with minimum attenuation (usually defined as less than 3dB (70.7%) of attenuation) Stopband - CORRECT ANSWER-frequencies not in a circuit's passband are in its stopband Cut-off frequency - CORRECT ANSWER-the cut-off frequency fc, (also called the critical frequency) separates passband and stopband Bandwidth (BW) - CORRECT ANSWER-width of the passband Roll-off - CORRECT ANSWER-rate at which attenuation increases/decreases after/before the cut-off frequency Vm - CORRECT ANSWER-amplitude (measured in V or A) omega - CORRECT ANSWER-2pif = angular frequency, rad/s f - CORRECT ANSWER-signal frequency, measured in Hertz (Hz) T - CORRECT ANSWER-1/f = signal period (length of time for 1 cycle) phi (Φ) - CORRECT ANSWER-phase (deg or rad) j - CORRECT ANSWER-sqrt(-1) Frequency response - CORRECT ANSWER-the variation in its behaviour with change in signal frequency resistance - CORRECT ANSWER-the friction against the flow of current reactance - CORRECT ANSWER-the inertia against the flow of current
