A new hybrid car was purchased by Pedernales Electric Cooperative as a courier vehicle to transport items between its 12 city offices. The car cost $35,000 and was retained for 5 years. Alternatively, it could have been retained for 100,000 miles. Salvage value is nil. Five-year DDB depreciation was applied. The car pool manager stated that he prefers UOP deprecia­tion on vehicles because it writes off the first cost faster. Use the actual annual miles driven, listed below, to plot the book values for both methods. Determine which method would have removed the $35,000 faster. Show hand or spreadsheet solution, as instructed.


DDB method does depreciate faster, but UOP, in this case, did depreciate slightly more of the first cost ($33,600 vs. $32,278).

In this problem, we study a T1 carrier system used in digital telephony. Voice signals are usually filtered using a low-pass filter of cut-off frequency 3.4 kHz and then sampled at 8 kHz. This system multiplexes samples from 24 voice signals in a single sampling period. Voice signals are coded with 8-bit PCM, and each frame (one sampling period) consists of 24 samples plus a single bit added for synchronization.

a. Calculate the duration of each bit. Note that this system multiplexes 24 samples each with 8 bits plus a single bit onto the time duration between two consecutive samples Ts = 1/ fs . b. Calculate the resulting transmission rate. Known quantities: Voice signals have bandwidth of 3.4 kHz and sampled at 8 kHz with an 8-bit quantizer. Each frame of the T-1 line consists of 24 voice channel samples plus a single bit for synchronization. Find: a) Duration of each bit. b) Transmission rate.
