A 12-bit mp3 with a sampling frequency of 28.8kHz is 4min and 20sec long. How large is the file in mega-bytes?
An 8 Mega-pixel camera uses 16-bit per pixel color resolution. What is the file size in mega- bytes produced by a single picture?
Solve for the reluctance of the center path of the transformer with the following dimensions. r = 1000
For the transistor circuit draw the DC circuit. ANS
Solve the DC circuit for the currents I B, I C, I E. V+ = 5vb = 120 R C = 1.06k R2 = 1.3k R L = 5k R E =410 R 1 = 136.6k ANS
For the transistor circuit draw the AC circuit ANS
Redraw the AC model replacing the transistor with the -model. iBiB
