A box contains 50 diodes of which 10 are known to be bad.
If the first diode drawn from the box was good, what is the probability that a second diode drawn will be good?
Design a common-emitter BJT amplifier with a gain of -100 (well above 3dB point) and a 3dB point at 100Hz. Assume beta = 100, Ic (quiescent) = 1mA, Vcc=20V. You can omit the output capacitor, but should bypass your emitter resistor.
an automobile travels 1200ft in 30s while being accelerated at a constant rate of 1.8 ft/s^2. Determine (a) its initial velocity, (b) its final velocity, (c) the distance traveled during the first 10s
Tones Input In To An Amplifier, Suppose two tones are input in to an amplifier. The tones are pure sinusoids with one at frequencies 8GHz and the other at frequency 8.03GHz,(delta f =0.03GHz).
Using the message signal m(t) = 1/(1+t^2) , determine and sketch the modulated signals for the following methods of modulation: (c) SSB modulation with only the upper sideband transmitted. (d) SSB modulation with only the lower sideband transmitted.
A digital signaling system is required to operate at 9600 bps. If a signaling element encodes a 8-bit word, what is the minimum required bandwidth of the channel?
The transfer function of a circuit is given by H(s)= 2s+4/4s^2+2s+2 a. Express the transfer function in a form in which the coefficients of the highest power of s are unity in both numerator and denominator.
The contects of a six-bit register are initially 100101. The register is shifted four times to the right, with the serial input being 1101. What are the contents of the register after each shift
(1) What is the difference between a series and a parallel circuit (2) How do you evaluate the total resistance of a parallel circuit
A 2.0 kg particle moves along the x axis. Its position varies with time according to x = t + 3.0t^3, Where x is in meters and t is in seconds. (a) Find the work done on the particlein the interval t = 0 to t = 1.70s.
Design a system using either a flow diagram or pseudo code that will accept a block of data words encoded as specified in Part 1; then check the parity for each data word and for the block. The system should output each of the 8-bit data words.
A digital communication system transmits one of the three values -1,0,1. A channel adds noise to cause the decoder to sometimes make an error. The error rates are 12.5% if a -1 is transmitted, 75% if a 0 is transmitted, and 12.5% if a 1 is transmi..
The laminated silicon steel core of a transformer has a mean length of 0.06 m and a cross section of 0.005 meter square. there are 150 turns on primary winding and 450 turns on the secondary. the input is 200 V rms at 50 Hz.
