Figure shows a system for batch processing. The system operations can be described as follows:
(1) A weighed quantity of dry material is added to liquid that has filled the tank to level L1.
(2) The mixture is stirred, and heat is applied to maintain the temperature between TL and TH for a period of 10 minutes.
(3) With the stir and heater off, the batch is emptied down to level L2. The whole process then starts again. Prepare a flowchart that describes the sequence of events. Be sure to consider any events that could occur in parallel.
write a program that prints a one-month calendar. the user specifies the number of days in the month and the day of the
What should the output voltage of the starter circuit be to reduce the starting torque until it equals the rated torque of the motor?
Design a common source amplifier, to solve a small signal voltage gain of at least Av= Vo/Vi= -10 Rl= 20k ohms, Rd= 200kohms. Assume the q point is chosen at Idq= 1mA, and Vdsq= 10V, Let Vtn= 2V, and lamda= 0.
Calculate the natural frequency requirements, if the damping ratios are 0.3 and 0.6 respectively. Determine the phase shift in each case at 50 and 75Hz
Consider a direct sequence spread spectrum (DSSS) system attempting to transfer data. The DSSS system has a data rate of 2 Kbps (2 thousand bits/sec) which is spread to 2 Mcps
The total current in a semiconductor is constant and is composed of electron drift current and hole diffusion current. The electron concentration is constant and is equal to 10^17 cm^-3. The hole concentration is given by p(x)
Find the probability that a randomly chosen grain weighs less than the mean gram weight.
Let the SNR be a parameter and express the SNR in decibels. As in Figure 7.8, assume a QDSB system. Repeat this exercise for a DSB system.
Design a 3 th order high - pass Butterworth filter with a High Frequency gain of 20 DB and a cutoff frequency of 20 rad/s. 2) Using MATLAB, plot the frequency respon se of this filter, and the location of the filter poles.
The current in the bulb depends on the time t according to the relation I = (0.807 A) sin [(272 rad/s)t]. (a) What is the frequency of the alternating current (b) Determine the resistance of the bulb's filament. (c) What is the average power deliv..
Show that the complex envelope of the sum of two bandpass signals (with the same carrier frequency) is equal to the sum of their individual complex envelopes.
Use Multisim and do an ac sweep from 10 Hz to 1 MHz, and then narrow your sweep until you find the frequency at which the minimum occurs and the output voltage at that frequency.
