ECE 2210 / 00 homework # 7 a 1st exam will include this material Answer the following problems on your own paper. 1. For each of the following sinusoidal waves, find: a)1) Peak-to-peak voltage or current, Vpp or Ipp 2) Amplitude, A, (Vp, or Ip) 3) Period, T 4) Frequency f in cycles/sec or Hz 5) An expression for v(t) or i(t) in terms of Acos(ωt + φ) (The frequency ω is in radians/sec the phase angle φ is in rad/sec or degrees) b) c) 2. For each of the following waveforms, find: 2a) 1) Peak-to-peak voltage or current, Vpp or Ipp 2) Average, (VDC, IDC, Vave, or Iave) 3) Period, T 4) Frequency f in cycles/sec or Hz b) c) 3.
