Show the truth table of the gates needed to control the PISO internal FF, has a load and shift signal. Use the behavior of load and shift in the notes. Assume a 4-bit PISO. The PISO is made up of a T-FF. You will focus on the FF producing Q2.
Homework Answers
The above figure represents the block diagram of 4 bit PISO register with T flip flop.
Now lets discuss how its work In Parallel In Serial Out (PISO) shift registers, the data is loaded onto the register in parallel format while it is retrieved from it serially.
Thus the bits of the input data word (Data in) appearing as inputs to the gates A2 are passed on as the outputs of OR gates at each individual combinational circuit. This causes the individual bits of the Data in to be loaded/stored into respective flip-flops at the appearance of first leading edge of the clock (except the bit B1 which gets directly stored into FF at the first clock tick). This indicates that all the bits of the input data word are stored into the register components at the same clock tick.

The task is to design a two-bit controlled counter which has two
counting bits (Q2, Q1), has one control input C1, and also two
extra outputs, one indicating overflow, the other underflow.
When C1=0 the counter counts up by 2s; i.e. 0 becomes 2, 1
becomes 3. In this mode the values 2 and 3 go to the overflow
state. When the control input C1=1, the counter counts down by 2s,
i.e. 3 becomes 1, and 2 becomes 0, and...

An information signal m(t) has highest frequency of W Hz and is sampled using a periodic pulse train p(t) made up of a rectangular pulse of width 1/8W seconds repeating at the Nyquist rate. a) Expand p(t) using a Fourier series expansion and use it to write the form for the sampled information signal mp(t). Put your result in the simplest possible terms. You may assume that p(t) is symmetric about t = 0. b) How would you recover m(t)...

number 4 and 5 please!
PROBLEM STATEMENT A logic circuit is needed to add multi-bit binary numbers. A 2-level circuit that would add two four-bit numbers would have 9 inputs and five outputs. Although a 2-level SOP or POS circuit theoretically would be very fast, it has numerous drawbacks that make it impractical. The design would be very complex in terms of the number of logic gates. The number of inputs for each gate would challenge target technologies. Testing would...
